Many people wonder if it is beneficial to listen to another language while sleeping. While it is not an efficient way to learn a language, some studies have shown that listening to recordings of word pairings while sleeping can help increase memory or develop new memories of word pairs. However, the quality of sleep is important, and if recordings are disrupting sleep, they may be doing more harm than good.

What You'll Learn
It can help you get used to the sounds of a new language
Listening to a new language while sleeping can help you get used to the sounds of that language. This phenomenon is called sleep learning, and it can be a powerful tool for language acquisition.
Research has shown that sleep, especially slow-wave sleep, strengthens neural connections related to recently learned language information. For example, a 2019 study found that subjects who listened to recordings of word pairs while sleeping could form associations between those words. The researchers played audio that associated a real word (e.g., "house") with a made-up word (e.g., "tofer"). When the subjects were awake, those recordings seemed to have an effect on their choices during a word association game. For instance, the subjects might implicitly know that a "tofer" is bigger than a "miljub" (a made-up word for brush) without knowing exactly what those made-up terms mean.
Additionally, listening to recordings of word meanings encountered before bed can also lead to learning that is demonstrated while awake. Swiss researchers discovered that when students listened to new foreign vocabulary words prior to sleeping, they had far greater results in memorizing them compared to participants who were awake for the same amount of time.
However, it is important to note that sleep learning should be combined with traditional methods to maximize progress and achieve success. Good sleep is essential for consolidating memories related to language study, but it is not enough on its own. Instead, taking a nap after learning new words or listening to recordings of previously learned material while sleeping can help improve memory recall and reinforce what has been learned.
Furthermore, the recordings should be familiar and several hours long so that they can be heard during deep sleep when the brain is most receptive. If the recordings wake you up or disrupt your sleep, they are probably doing more harm than good.

It may help you remember new words
Sleep plays a crucial role in consolidating our memories, integrating new information with our existing knowledge to help us remember it in the long term. During sleep, neurons in our brain associated with memories fire, replaying these memories. This process can be influenced by what we hear while we sleep, even if we are not consciously aware of it.
Research has shown that listening to new words during sleep can help us remember them. In one study, participants were exposed to new, made-up words associated with actual words during slow-wave sleep. When they woke up, they were able to correctly categorise those words. Another study found that subjects who listened to recordings of word pairs while sleeping could form associations between those words. For example, if they heard the word "house" paired with a made-up word like "tofer", they would implicitly know that a "tofer" is bigger than a "miljub" (a made-up word for a brush).
However, it is important to note that simply listening to a foreign language while sleeping will not make you fluent. Language learning requires understanding the structure, grammar, and vocabulary of the language, which cannot be achieved solely through passive listening during sleep. Additionally, the recordings should be of material that you are already familiar with, such as a recording of your language class. This is because you are trying to access the episodic memory of learning, and replaying the class audio will help with that.
There are also some practical considerations to keep in mind. Firstly, you don't want the noise to wake you up, so it should not be played too loud. Secondly, some people find headphones uncomfortable at night, so it may be better to play the material out loud. Finally, you should set a timer for the recording to start about half an hour after you fall asleep, and it should be long enough to still be playing during non-REM sleep, so a few hours long.
While listening to a foreign language during sleep may help with memory consolidation and forming associations between words, it should be combined with other active language-learning methods for the best results.

It could interfere with your sleep
Listening to a language recording while sleeping can interfere with your sleep. If the recording wakes you up, it is doing more harm than good. For example, one person who tried this method reported that they woke up in the middle of the night, feeling confused after hearing a disembodied voice in their dream.
To avoid this, it is recommended that you play the recording at a low volume and start it half an hour after you fall asleep. However, even if you manage to avoid being woken up by the recording, it may still interfere with your sleep cycle. Sleep is when your brain consolidates memories, and if you are replaying language lessons in your sleep, you may have a harder time remembering other new information.
Additionally, it is important to note that simply playing a language recording while you sleep will not make you fluent. Language learning requires understanding the structure, grammar, and vocabulary of a language, which cannot be achieved solely through passive listening during sleep. While there is some evidence that listening to language recordings during sleep can help reinforce new languages, it should be combined with conscious, active efforts to learn the language, such as taking classes or using a language learning program.

It can cause strange dreams
Listening to a foreign language while sleeping can cause strange dreams. One person who tried this method reported that they woke up at 3 a.m., feeling confused and hearing a voice but not really comprehending it. They also mentioned having weird dreams that night.
This phenomenon may be due to the brain's natural process of consolidating memories during sleep. When we sleep, neurons in our brain associated with memories fire up, replaying and strengthening those memories. If we introduce new information, such as a foreign language, during this process, it can interfere with the brain's natural replay of memories, potentially leading to unusual dreams or even affecting our ability to remember other new information.
Additionally, the effectiveness of learning a language during sleep is questionable. While some studies suggest that we can form associations between words of a foreign language and our native language, simply listening to a foreign language while sleeping is not enough to become fluent. Learning a language requires understanding its structure, grammar, and vocabulary, which are best achieved through conscious, active learning methods such as taking classes or using language learning programs.
However, listening to recordings of familiar language lessons or words while sleeping may help reinforce what has been previously learned. It is recommended to play these recordings a few hours long, starting about half an hour after falling asleep, to ensure they are heard during slow-wave sleep when the brain is most receptive.
Overall, while it may be possible to influence our dreams and memory consolidation by listening to a foreign language during sleep, the effectiveness of language learning through this method is limited and may even cause unintended consequences, such as strange dreams or interference with the memory of other new information.

It's more effective when combined with daytime learning
While it is tempting to believe that we can learn a language in our sleep, the reality is that language learning requires conscious, active effort. However, sleep can be a great supplement to daytime learning.
Research has shown that listening to recordings of new vocabulary while sleeping can help reinforce language lessons learned during the day. This is because sleep is when people consolidate memories, integrating new information with existing knowledge for long-term recall. For example, a 2019 study found that subjects who listened to recordings of word pairs while sleeping could form associations between those words. When awake, the subjects made choices that reflected the word associations they had heard during sleep, even if they did not consciously remember hearing them.
However, it is important to note that this method of reinforcement only works with familiar vocabulary. If you play recordings of entirely new words, you are unlikely to benefit. Therefore, it is recommended to play recordings of language lessons or other familiar material. Ideally, these recordings should be a few hours long to ensure that you hear them during slow-wave sleep, when the brain is most receptive.
Additionally, it is important to ensure that the volume is not too loud, as you do not want the noise to wake you up. Some people find headphones uncomfortable, so playing the recording out loud may be preferable. You can also set a delay on the recording so that it starts playing about half an hour after you fall asleep.
While listening to a language during sleep can be a helpful supplement to daytime learning, it is not a replacement for conscious, active learning. A good night's sleep is essential for effective language learning during the day, so if you find that playing recordings at night is disrupting your sleep, it is probably doing more harm than good.

Frequently asked questions
While there is some evidence that listening to a language while sleeping can help reinforce what you have learned during the day, it is not a simple yes or no. It is important to get a good night's sleep, and if the recordings are disrupting your sleep, they are probably doing more harm than good.
Sleep helps to consolidate what you have learned during the day. Research has found that people who took a nap after learning word pairs remembered what they had learned better than those who stayed awake. So, if you are learning a new language, it is a good idea to take a nap after your study session.
If you want to try listening to another language while sleeping, it is recommended that you choose recordings of material you are already familiar with. The recordings should be a few hours long to make sure you hear them during slow-wave sleep, which is when your brain is most receptive. It is also advised to play the recordings over a speaker instead of headphones and to put a half-hour delay on the start of the recordings so they do not interfere with you falling asleep.
