Text-to-speech via 9Router /v1/audio/speech using OpenAI / ElevenLabs / Deepgram / Edge TTS / Google TTS / Hyperbolic / Inworld voices. Use when the user wants to convert text to speech, generate audio, voiceover, narrate, or read text aloud.
安装前可以查看交给 AI 代理的指令内容。
Requires NINEROUTER_URL (and NINEROUTER_KEY if auth enabled). See https://raw.githubusercontent.com/decolua/9router/refs/heads/master/skills/9router/SKILL.md for setup.
# 1) List models
curl $NINEROUTER_URL/v1/models/tts | jq '.data[].id'
# 2) Per-model metadata (params, voicesUrl if voice-by-id)
curl "$NINEROUTER_URL/v1/models/info?id=el/eleven_multilingual_v2"
# 3) List voices (elevenlabs, edge-tts, deepgram, inworld, local-device). Optional ?lang=vi
curl "$NINEROUTER_URL/v1/audio/voices?provider=edge-tts&lang=vi" | jq '.data[].model'
model field in /v1/audio/speech = voice ID directly (e.g. edge-tts/vi-VN-HoaiMyNeural, el/<voice_id>, or openai/tts-1 model+default voice).
POST $NINEROUTER_URL/v1/audio/speech
| Field | Required | Notes |
|---|---|---|
model | yes | voice ID from /v1/models/tts |
input | yes | text to speak |
Query ?response_format=mp3 (default, raw bytes) or ?response_format=json ({audio: base64, format}).
Save MP3:
curl -X POST "$NINEROUTER_URL/v1/audio/speech" \
-H "Authorization: Bearer $NINEROUTER_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"openai/tts-1","input":"Hello world"}' \
--output speech.mp3
JS (save file):
import { writeFile } from "node:fs/promises";
const r = await fetch(`${process.env.NINEROUTER_URL}/v1/audio/speech`, {
method: "POST",
headers: { "Authorization": `Bearer ${process.env.NINEROUTER_KEY}`, "Content-Type": "application/json" },
body: JSON.stringify({ model: "el/eleven_multilingual_v2", input: "Xin chào" }),
});
await writeFile("speech.mp3", Buffer.from(await r.arrayBuffer()));
Default → raw audio bytes (Content-Type audio/mp3).
?response_format=json:
{ "audio": "SUQzBAAAA...", "format": "mp3" }
| Provider | model format | Notes |
|---|---|---|
openai | tts-1/alloy (model/voice) or just voice | Default model gpt-4o-mini-tts |
elevenlabs | <model_id>/<voice_id> or <voice_id> | Default model eleven_flash_v2_5; list voices in Dashboard |
openrouter | openai/gpt-4o-mini-tts/alloy | Streamed via chat-completions audio modality |
edge-tts | voice id e.g. vi-VN-HoaiMyNeural | noAuth; default vi-VN-HoaiMyNeural |
google-tts | language code e.g. en, vi | noAuth |
local-device | OS voice name (say -v ? / SAPI) | noAuth; needs ffmpeg |
deepgram | aura-asteria-en etc | Token auth |
nvidia, inworld, cartesia, playht | model/voice | Provider-specific auth header |
coqui, tortoise | speaker / voice id | Localhost noAuth |
hyperbolic | model id | Body = {text} only |
