murmr

Python SDK for the murmr TTS API. Async-first with full sync support.

pip install murmr

Quick Start

Voice Design (describe any voice in natural language)

from murmr import MurmrClient

client = MurmrClient(api_key="murmr_sk_live_...")

# Generate speech with a voice description
wav = client.voices.design(
    input="Hello, welcome to murmr!",
    voice_description="A warm, friendly female voice with a slight British accent",
)

with open("output.wav", "wb") as f:
    f.write(wav)

Saved Voices (batch via RunPod Serverless)

# Submit a batch job
job = client.speech.create(input="Hello world", voice="voice_abc123")

# Wait for completion
result = client.speech.create_and_wait(input="Hello world", voice="voice_abc123")
audio = result.audio_bytes  # decoded WAV

Streaming

# Stream PCM audio chunks
with client.speech.stream(input="Hello world", voice="voice_abc123") as stream:
    for chunk in stream:
        pcm = chunk.audio_bytes  # 24kHz mono 16-bit PCM
        if chunk.done:
            break

Async

import asyncio
from murmr import AsyncMurmrClient

async def main():
    async with AsyncMurmrClient(api_key="murmr_sk_live_...") as client:
        wav = await client.voices.design(
            input="Hello from async!",
            voice_description="A deep male voice",
        )

asyncio.run(main())

Long-Form Audio

# Automatically chunks, retries, and concatenates
result = client.speech.create_long_form(
    input=very_long_text,
    voice="voice_abc123",
    on_progress=lambda current, total, pct: print(f"{pct}%"),
)

with open("long_form.wav", "wb") as f:
    f.write(result.audio)
