Text-to-Speech

Text-to-speech (TTS) lets you generate audio for your flashcards without recording your own voice. It is great for quick creation or when you want a consistent voice across a folder.

Create a card with TTS​

  1. Open a folder and tap Add Card.
  2. Enter the front text and back text.
  3. Choose Text-to-Speech for the audio source.
  4. Pick a voice and preview it.
  5. Review and finish the card.

Text-to-speech sources​

You can choose a TTS source in Settings > Text-To-Speech and set Side Correspondence so the app uses the right voice for each side:

  • On Device: Uses the voices installed on your phone.
  • Amazon Polly: Cloud voices with wider language options.
  • OpenAI TTS: Natural voices with multiple styles.

Download more iOS voices​

iOS includes many built-in voices, but some are optional downloads. You can add more voices (including enhanced ones) from the system Settings app, and they will appear in your on-device voice list. Personal Voices and Siri Voices are not available for use in Audio Flashcards.

  1. Open Settings on your iPhone or iPad.
  2. Go to Accessibility > Read & Speak > Voices.
    On older iOS versions this may appear as Spoken Content.
  3. Choose a language to see its available voices.
  4. Tap the download icon (cloud with arrow) next to any voice you want to add.
    You can preview voices with the play button. Enhanced voices are larger and may require Wi-Fi.

Once downloaded, these voices are available system-wide, including in Audio Flashcards.
