pipecat-supertonic 0.1.1

Supertonic TTS service integration for Pipecat (Unofficial)

pipecat-supertonic

pipecat-supertonic provides a Pipecat-compatible TTSService wrapper for the official Supertonic Python SDK.

The package is designed to feel like a native Pipecat service:

• import with from pipecat_supertonic import SupertonicTTSService
• configure with SupertonicTTSService.Settings(...)
• drop directly into an existing Pipecat pipeline

This project is an independent community integration maintained by Archit Jambhule. It is not affiliated with Supertone or the Supertonic team.

Install

pip install pipecat-supertonic

Or with uv:

uv add pipecat-supertonic

Supported Voices

F1, F2, F3, F4, F5, M1, M2, M3, M4, M5

Basic Usage

from pipecat_supertonic import SupertonicTTSService

tts = SupertonicTTSService(
    settings=SupertonicTTSService.Settings(
        voice="M1",
        language="en",
        total_steps=5,
        speed=1.05,
    )
)

await tts.warmup()

warmup() is required before the service is used in a live Pipecat pipeline. Call it during application startup so Supertonic can download and cache the model before the first user request arrives.

Pipecat Pipeline Usage

Use SupertonicTTSService anywhere Pipecat expects a TTS processor:

from pipecat.pipeline.pipeline import Pipeline
from pipecat_supertonic import SupertonicTTSService

tts = SupertonicTTSService(
    settings=SupertonicTTSService.Settings(
        voice="M1",
        language="en",
        total_steps=5,
        speed=1.05,
    )
)

await tts.warmup()

pipeline = Pipeline(
    [
        transport.input(),
        stt,
        llm,
        tts,
        transport.output(),
    ]
)

Warmup Contract

This package intentionally does not lazy-load Supertonic during active TTS requests. If the service is used before warmup(), it fails fast with a clear error telling the caller to warm the service up first.

This avoids first-request cold-start delays and keeps Pipecat TTS frame ordering stable.

Foundational Example

examples/voice-supertonic.py synthesizes a short utterance and writes the generated PCM audio to examples/supertonic-demo.wav.

Run it from the repository root:

uv sync --group dev
uv run python examples/voice-supertonic.py

Compatibility

Tested with pipecat-ai==1.2.0 and supertonic==1.2.1.

Development

uv sync --group dev
uv run pytest
uv run ruff check .
