I'm experiencing technical issues whilst using the conversational AI. What can I do?

Langua combines numerous emerging technologies from external providers. These occasionally have outages or errors. Sometimes they also conflict with certain devices & browsers.

Under each issue below, there are solutions that have usually worked for other learners, such as ensuring you're on the latest iOS if you use a device from Apple, using Chrome (if you're using another browser), or switching from the website to the latest mobile app.

If none of the solutions work for you, or you have another issue, please don't hesitate to get in touch with our team via email or via the Help/Contact button in the bottom right. Can't see it? Click here to open the contact form). Using the help widget? Click 'Contact' at the top).

I am not receiving a response / I am seeing an error message after I reply

Very occasionally, one of our many technology providers will have some instability or a full outage. Try changing the 'AI model' in the Chat Settings. Note this is hidden under Advanced Settings if you're on the mobile app.

The 'V2' model was created by a different company to 'V1', so switching can help if there is an outage with V1. We may also switch you automatically if we detect an issue.

Sometimes, the original error prevents the conversation from continuing even after you switch model and refresh the page. In this case, you'll need to start a new conversation via 'Speak' in the menu (or clicking back).

If you're experiencing the issue on multiple days, please do send our support team a message so we can investigate. We know how frustrating it is when this issue occurs, and are hoping the AI providers improve the stability of their tech.

Occasionally, the issue can be fixed by clearing your Cookies. See the instructions at the bottom of this article for how to do this in a few clicks.

Note that whilst the average response time is only a few seconds, if the AI is preparing an unusually long reply (for example answering a grammar question), it may take 10+ seconds.


I cannot hear the audio properly

The volume can progressively go lower on very long messages, however this is rare and does not normally occur on standard length replies (2-4 sentences). The voice tech company we use is working on fixing that.

We occasionally hear that on certain iPad and iPhone models, the volume is continuously very low when Langua is used via the web browser. This seems to be related to something in the browser conflicting with the autoplayed voice technology we integrate into the conversational AI. If you are experiencing this issue whilst using our website, we strongly recommend using our mobile app instead. Please see here for more info on the mobile apps.

Below, you can also see solutions that have sometimes worked for others:

1) check that you have the latest iOS. Feel free to contact us with your device info if you do not know how to update the OS. It is usually found in the Settings section on your device.

2) ensure the volume is maximised on your device. We've noticed that certain devices (usually not Apple ones) will increase the call volume rather than media volume, in which case you have to click the 3 vertically aligned dots on the screen to get to the media volume.

3) try clearing your cookies/cache for LanguaTalk - see here for how to do this.

4) The volume can also vary by voice, so you may want to try changing the voice before you start the chat via 'change conversation settings' at the bottom (before you start a conversation).

Note that changing from Safari to another browser does not make a difference because Apple restricts other browsers to use Apple's specific technology (Chrome on Apple is not the real deal).

If you're using earphones via bluetooth, this will not work on Apple devices if you are using Langua via the web browser. The solution here is to use the mobile app, as the issue is related to how Apple devices process the audio on web browsers.



I cannot record what I say.

If you're using the web version, please click here for solutions. Otherwise, continue to read for mobile app specific support:

  1. Go to your phone's settings, find "Microphone" permissions, and ensure Langua is enabled. Ideally set to 'always allow' so that it doesn't switch off.
  2. If resetting the mic permission doesn't work, try removing and reinstalling the app
  3. Try switching transcription model in Chat Settings - we offer technologies from multiple providers. Occasionally, one of them will have brief downtime.
  4. Check you're not on an old version of the Langua app. To do this, go to Langua on the Play Store and check whether it says 'Update' rather than 'Open'.
  5. Users of certain Android devices (e.g. Xiaomi and Motorola) have been able to solve the problem by doing the following:
    1. Go to Settings → Privacy → Permission Manager → Microphone
    2. Find Google Assistant (sometimes called OK Google), and set it to "Don't allow" or "Always ask". For Xiaomi devices, also check Xiao AI is off and for Motorola, Moto Voice. All of these services can conflict with recording in apps like ours.
    3. Make sure Langua has microphone permission enabled
    4. Verify you're not running an outdated version of Android (check under Settings).

I cannot record myself on the website version

Internet browsers sometimes remove microphone access and can be unstable, particularly on Apple devices. We recommend using our mobile app instead for a more reliable experience. If you really want to use the web version, please see some possible solutions below:

Quick fixes:

  • Try using Chrome or Brave browsers instead of Safari or Edge.
  • Refresh the page, as sometimes the "blocked" message appears by mistake
  • Open Langua in a new tab, or in an incognito
  • Clear your cookies/cache - see how at the bottom of this article.
  • Try switching transcription model in Chat Settings - we offer technologies from multiple providers. Occasionally, one of them will have brief downtime.

Browser-specific solutions:

Chrome/Firefox (Desktop):

  • Look for a microphone icon at the top of your browser, just to the left of the website address

  • Click this icon and select "Permissions" or "Microphone" to enable access.

Need help on Chrome? See advice from Google (creator of Chrome).

Apple devices:

  • Go to Settings → Safari → Microphone (sometimes under 'Websites')
  • Make sure "LanguaTalk" is set to Allow
  • If already on Allow, switch to Deny and back to Allow
  • For Macs: Also check your Sound Settings to ensure your microphone input volume isn't muted.
  • For iPhone & iPad, it should also be possible to see the mic icon on the tab that has the chat open. You can disable and enable by clicking on the mic icon.
  • If the above steps don't work, consider updating to the latest operating system if you are not on it, as Apple doesn't always maintain audio well on older versions.

I'm seeing text from the previous message - it doesn't match the audio

We've heard of this issue occurring occasionally for users when accessing Langua via the Edge browser. Switching to Google Chrome has usually fixed their issue, so give it a try.
