vision-agents-plugins-kokoro 0.3.8

Kokoro TTS integration for Vision Agents

GetStream Kokoro Plugin

This package integrates the open-weight Kokoro-82M TTS model with the GetStream audio/video SDK.

It provides a drop-in KokoroTTS class that implements the common getstream_common.tts.TTS interface, allowing you to stream PCM audio generated by Kokoro directly into a WebRTC AudioStreamTrack.

from getstream.plugins.kokoro import KokoroTTS
from getstream.video.rtc.audio_track import AudioStreamTrack

track = AudioStreamTrack(framerate=24_000)

tts = KokoroTTS(lang_code="a", voice="af_heart")
tts.set_output_track(track)

await tts.send("Hello from Kokoro!")

Installation

pip install getstream-plugins-kokoro

This will pull in the required kokoro, numpy and getstream[webrtc"] dependencies. You also need espeak-ng at runtime for pronunciation fallback. On macOS you can install it with Homebrew:

brew install espeak-ng

Configuration options

Parameter	Default	Description
lang_code	"a"	Language group passed to KPipeline ("a" = American English, etc.)
voice	"af_heart"	Kokoro voice preset. See the model card for available options.
speed	1.0	Playback speed multiplier.
sample_rate	24000	Output sample-rate (fixed by Kokoro). The attached AudioStreamTrack must use the same value.
