@absolutejs/voice-rime

Rime text-to-speech adapter for @absolutejs/voice.

@absolutejs/voice is a runtime dependency.

Use

import { voice } from "@absolutejs/voice";
import { rime } from "@absolutejs/voice-rime";

const app = voice({
  // ... stt + other voice options ...
  tts: rime({
    apiKey: process.env.RIME_API_KEY!,
    speaker: "cove",
    // optional:
    modelId: "mistv2",           // default; or 'mist' / 'arcana'
    audioFormat: "pcm",          // default; or 'mulaw' for telephony
    sampleRate: 22_050,          // default
    speedAlpha: 1.0,
    lang: "eng",
    reduceLatency: true,
    pauseBetweenBrackets: true,

Notes

• session.close(reason) aborts in-flight requests and refuses further sends.
• This adapter targets Rime's HTTP streaming endpoint. If you need their WebSocket transport, open an issue.
