Lmnt Generate Speech With Metadata

Generates speech from text and returns JSON with base64-encoded audio and optional word-level timing metadata. Use when you need the synthesis seed or word timestamps for subtitle synchronization. For lower latency without metadata, use the Synthesize Speech action instead.

Inputs

  • seedinteger
    Integer seed for reproducible speech variations. Use the same seed to replicate a specific output.
  • textstring
    Required
    The text to synthesize into speech (max 5000 characters including spaces).
  • debugboolean
    When true, saves the synthesis clip to your clip library for debugging purposes.
  • modelstring
    The synthesis model to use (default: 'blizzard').
  • top_pnumber
    Controls speech stability (0-1 range, default: 0.8). Lower values produce more consistent speech.
  • voicestring
    Required
    The voice ID to use for speech synthesis (e.g., 'lily', 'leah', 'daniel'). Use the List Voices action to get available voice IDs.
  • formatstring
    Output audio format. Streamable formats (generate faster): mp3 (default), ulaw, webm, pcm_s16le, pcm_f32le. Non-streamable: aac, wav.
  • languagestring
    ISO 639-1 two-letter language code (e.g., 'en', 'es', 'fr'). Auto-detected by default, but specifying language improves generation speed.
  • sample_rateinteger
    Audio sample rate in Hz. Options: 8000, 16000, or 24000.
  • temperaturenumber
    Controls speech expressiveness (numeric value, default: 1.0). Higher values increase variation.
  • return_durationsboolean
    When true, returns word-level duration timestamps in the response. Useful for synchronizing subtitles or animations with speech.

Observable output

  • data
    Required
    Data from the action execution
  • errorstring
    Error if any occurred during the execution of the action
  • successfulboolean
    Required
    Whether or not the action execution was successful or not
