Usage

​
Basic Setup

from pipecat.services.groq import GroqTTSService

tts = GroqTTSService(
    api_key=os.getenv("GROQ_API_KEY"),
    settings=GroqTTSService.Settings(
        voice="autumn",
    ),
)

​
With Custom Settings

from pipecat.transcriptions.language import Language

tts = GroqTTSService(
    api_key=os.getenv("GROQ_API_KEY"),
    settings=GroqTTSService.Settings(
        model="canopylabs/orpheus-v1-english",
        voice="autumn",
        language=Language.EN,
        speed=1.2,
    ),
)
The InputParams / params= pattern is deprecated as of v0.0.105. Use Settings / settings= instead. See the Service Settings guide for migration details.

​
Notes

  • Fixed sample rate: Groq TTS only supports 48kHz sample rate. Setting a different value will produce a warning.
  • WAV output: The service outputs WAV-formatted audio, which is decoded internally to extract raw PCM frames.
