Language-learning apps increasingly promote a very appealing idea: if your goal is to speak Spanish, the most efficient solution is to start speaking immediately. Have realistic conversations, receive instant corrections and gradually become fluent through practice.
There is an important truth behind this message. Nobody develops conversational fluency without speaking, and learners who spend all their time studying rules may struggle to use them spontaneously. However, speaking practice and language learning are not interchangeable. A conversation gives you an opportunity to use the language you already possess. It does not necessarily provide you with the knowledge required to express something new.
This distinction is particularly important for adult learners, who often have limited time and want to see practical progress. More speaking can certainly help, but only when conversation forms part of a coherent learning process.
Why instant correction feels like learning
When an app corrects a sentence immediately, the interaction creates a powerful impression of progress. You said something incorrectly, the app supplied a better version and you understood the correction.
However, recognising the correct sentence when it appears on a screen is very different from retrieving and using it independently several days later.
Imagine that a learner says:
Ayer he ido a una reunión.
The app might replace this with:
Ayer fui a una reunión.
The learner can probably see that the second sentence is correct, but several questions remain unanswered. Why is fui more appropriate here? When should he ido be used? Does the distinction operate in exactly the same way throughout the Spanish-speaking world? Which time expressions normally accompany each tense?
Most importantly, will the learner remember and apply the correction during the next spontaneous conversation?
A correction can identify a problem. It does not automatically provide the explanation, carefully chosen examples, retrieval practice and repeated use needed to turn the corrected form into something the learner genuinely controls.
Research into second-language teaching has consistently found that focused instruction produces substantial gains and that explicit instruction is generally more effective than relying exclusively on implicit exposure (Norris & Ortega, 2000). A later meta-analysis also found advantages for explicit instruction across both simple and complex grammatical features (Spada & Tomita, 2010).
This does not mean returning to endless grammar tables or translating disconnected sentences. It means helping learners notice, understand and practise useful patterns before expecting them to use those patterns spontaneously.
Correction is useful, but correction is not a curriculum
Corrective feedback can support language development. The evidence does not justify the claim that corrections are ineffective. It does, however, show that their effectiveness depends on how they are delivered and what happens afterwards.
A major meta-analysis of corrective feedback found that correction can have meaningful and lasting effects, while also identifying important differences related to the setting, type of feedback and way learning is measured. Classroom research has similarly found that oral corrective feedback can be effective, with some forms of prompting learners to produce the correct language themselves generating stronger results than simply supplying the answer (Lyster & Saito, 2010).
The relevant question is therefore not whether learners should be corrected. It is whether the correction is:
- appropriate for their present level;
- connected to something they are learning;
- understandable at the moment it is given;
- important enough to interrupt the conversation;
- followed by opportunities to retrieve and reuse the language;
- revisited later, before it is forgotten.
When an app corrects every sentence, it may produce an impressive quantity of feedback without creating a clear learning sequence.
What happens when everything is corrected
An adult learner trying to communicate may simultaneously be choosing vocabulary, arranging a sentence, conjugating verbs, monitoring pronunciation and deciding what to say next. If every error produces another correction, the learner receives more information than can realistically be processed during the conversation.
This can create a familiar cycle:
- The learner tries to express an idea beyond their current linguistic resources.
- Several corrections appear.
- The learner understands them momentarily.
- The conversation continues before the corrected language has been practised.
- The same errors return during the next conversation.
- The learner begins to believe that they are “bad at languages”.
The learner has been active throughout the session. They may have spoken for twenty or thirty minutes and received dozens of corrections. Nevertheless, very little of that new language has become independently available.
Activity is not the same as learning, just as understanding is not the same as remembering.
Constant interruption can also make speaking progressively less enjoyable. The learner starts monitoring every word, anticipating the next correction and avoiding structures that might produce mistakes. A tool intended to increase confidence can therefore make the learner more hesitant.
A good teacher does not correct everything simply because correction is possible. Corrections should be selected according to what the learner already knows, what they are currently learning and which changes will make the greatest difference to their communication.
Conversation needs scaffolding
Language learning works best when new material is connected to an existing foundation. Learners encounter something unfamiliar, understand how it relates to what they already know and then use it in increasingly independent contexts.
Grammar and vocabulary provide essential parts of that foundation. They are not the finished building, but removing them does not make construction faster.
Consider the Spanish present perfect. A learner might first examine how forms such as he visitado, has probado and ha aprendido are constructed and used. The teacher can then introduce controlled but meaningful questions:
- ¿Has ido alguna vez a China?
- ¿Qué has hecho esta semana?
- ¿Has aprendido algo interesante recientemente?
- ¿Has hablado con algún cliente hoy?
The learner is already communicating, but the task gives them a manageable objective and repeated opportunities to retrieve the same structure.
The activity can then become more imaginative:
¿Qué ha hecho una persona que se ha convertido en un gran cocinero?
Possible answers might include:
- Ha viajado a muchos países.
- Ha probado platos muy diferentes.
- Ha trabajado en varios restaurantes.
- Ha aprendido de otros cocineros.
- Ha cometido muchos errores.
- Ha creado sus propias recetas.
The learner is producing original language, making inferences and expressing meaningful ideas. At the same time, the activity has been carefully designed to generate repeated use of a particular grammatical structure and a relevant body of vocabulary.
The next step might be a freer conversation about travel, professional experience or personal achievements. By that stage, the learner is no longer trying to invent every component of every sentence simultaneously. Conversation consolidates knowledge that has already been introduced and practised.
Research into effective second-language practice emphasises that repetition alone is insufficient. The type of practice, its distribution over time, the need to retrieve language and the contexts in which it will eventually be used all influence learning (Suzuki, Nakata & DeKeyser, 2019).
Structured practice can still be authentic
Language-learning marketing often treats “real-life conversation” and structured study as opposites. According to this presentation, learners must choose between artificial grammar exercises and natural communication.
This is a false choice.
A structured lesson about professional experience can prepare an adult learner to:
- describe previous jobs and responsibilities;
- explain what they do in their present role;
- discuss recent projects;
- describe achievements and setbacks;
- distinguish between completed and continuing experiences;
- ask appropriate follow-up questions;
- respond more confidently during professional conversations.
These are authentic communicative objectives. They can also be organised so that each activity recycles specific grammar and vocabulary from previous lessons.
The British Council’s speaking resources illustrate this principle clearly. Learners work at an appropriate level, observe useful language in a recognisable situation, complete preparatory activities and then practise the expressions they will need. Speaking is central, but it sits inside a structured progression.
Meaningful communication and careful lesson design should support one another.
The problem with “just start speaking”
Some current language apps promise to get learners speaking from their first lesson, hold realistic AI conversations and provide immediate personalised feedback. Speak, for example, places speaking from the first lesson at the centre of its marketing, while ELSA promotes realistic role plays combined with instant AI feedback.
These features can be genuinely useful. Speaking from an early stage can reduce inhibition, pronunciation technology can reveal problems learners may not notice themselves, and AI offers a convenient way to rehearse familiar situations.
The misleading expectation arises when speaking and correction are presented as though they automatically produce progression.
Some apps do offer carefully sequenced courses, and this should not be dismissed. A well-designed curriculum can introduce language progressively, recycle previous material and provide far more direction than completely open-ended conversation. However, even a strong app curriculum is designed for a broad population of learners. It cannot always determine why a particular person is struggling, decide when an explanation needs to be approached differently or continually reshape the course around that learner’s professional objectives, existing knowledge and recurring difficulties.
Someone (or a genuinely coherent curriculum) must still determine:
- what the learner is ready to study;
- which vocabulary will be most useful;
- how new language connects to previous knowledge;
- which mistakes currently matter;
- what requires further explanation;
- when guided practice should become freer conversation;
- which material needs to be revisited later.
A structured app can provide a curriculum. A skilled teacher can interpret, adapt and continually reshape that curriculum around the individual learner.
Without that adaptation, learners may become increasingly skilled at navigating conversations with the same limited repertoire while continuing to repeat the same grammatical and lexical problems.
Where language apps can genuinely help
Language apps can be valuable when their role is understood correctly. They can provide:
- additional listening practice;
- pronunciation rehearsal;
- convenient vocabulary revision;
- repeated exposure to common expressions;
- low-pressure opportunities to speak aloud;
- simulated professional or travel situations;
- extra practice between lessons.
AI conversations may be especially useful for adults who want to rehearse familiar material without feeling observed or judged. They also make regular contact with Spanish easier for learners with demanding professional schedules.
A well-designed app can be an excellent source of additional practice between lessons. Its value increases when learners understand where it fits within a broader learning process and how to use it in relation to their individual goals.
The problem begins when a practice tool is treated as a complete learning method.
An app can generate an unlimited number of conversations, but quantity does not guarantee progression. If learners repeatedly attempt tasks for which they lack the necessary grammar and vocabulary, correction becomes a reaction to failure rather than part of a planned learning process.
A useful app should supplement learning. It should not be expected to replace a carefully constructed sequence of explanation, guided practice, retrieval, recycling and communication.
What effective adult Spanish learning looks like
Adult learners usually have limited time and clear reasons for studying Spanish. They may want to communicate with clients, work abroad, speak with relatives, travel more independently or return to a language they studied years ago.
Their learning should therefore be practical, but practical does not mean improvised.
An effective programme combines:
- clear linguistic and communicative objectives;
- vocabulary selected for the learner’s real needs;
- concise grammatical explanation;
- carefully designed guided practice;
- regular retrieval of previously studied language;
- meaningful conversation;
- selective correction;
- repeated exposure over time;
- opportunities to use the language in new contexts.
Speaking remains indispensable. It is one of the principal ways in which knowledge becomes accessible, flexible and increasingly automatic. However, asking someone to speak without first giving them the necessary linguistic resources is like asking them to construct a building while supplying each missing brick only after they have tried—and failed—to use it.
Good teaching provides the materials, strengthens the framework and creates frequent opportunities to build with increasing independence.
Conversation is where the language comes alive. Structure is what allows that conversation to develop.
