Providers

所有 Provider 共享凭证形态（@ottervoice/provider-utils）：

字段	用途
apiKey	服务端长期密钥（禁止下发客户端）
tokenBrokerUrl	客户端请求短期 token
fetch	可注入

能力对照

能力	包	传输
Streaming ASR	@ottervoice/provider-deepgram	WebSocket
Streaming ASR	@ottervoice/provider-elevenlabs	WebSocket
LLM / SSE	@ottervoice/provider-openrouter	HTTP SSE
TTS / STT / Audio LLM	@ottervoice/provider-openrouter	HTTP（Demo 可选）
TTS	@ottervoice/provider-azure-speech	REST + SSML

自定义 ASR 必须正确声明 capabilities.streaming，core 据此选择 live 分片或完整轮次音频。

import { createDeepgramASR } from '@ottervoice/provider-deepgram';
import { createOpenRouterLLM } from '@ottervoice/provider-openrouter';
import { createAzureTTS } from '@ottervoice/provider-azure-speech';

const asr = createDeepgramASR({ tokenBrokerUrl: '/api/voice/token' });
const llm = createOpenRouterLLM({
  tokenBrokerUrl: '/api/voice/token',
  model: 'openai/gpt-4o-mini',
});
const tts = createAzureTTS({
  region: 'eastasia',
  voice: 'zh-CN-XiaoxiaoNeural',
  tokenBrokerUrl: '/api/voice/token',
});
