puts response.read_body将文本转换为语音。返回的是原始音频字节（
audio/mpeg），而不是 JSON。
响应内容是一个二进制 MP3 文件，而不是 JSON 对象。
Content-Type 响应头为 audio/mpeg。身份验证
需要提供 Bearer 令牌。详见身份验证。请求体
string
必填
要转换为语音的文本。最多 4,096 个字符。
string
默认值:"theo-voice-classic"
可选的 Theo 语音标识符。省略则使用默认语音。未知的取值会回退到
theo-voice-classic。| 语音 | 特点 |
|---|---|
theo-voice-classic | 中性、多用途——默认音色 |
theo-voice-bright | 明亮、清晰、活泼 |
theo-voice-storyteller | 叙事感强、富有表现力 |
theo-voice-deep | 低沉、权威 |
theo-voice-warm | 温暖、专业 |
theo-voice-soft | 柔和、沉稳 |
number
默认值:"1.0"
播放速度倍率（0.25–4.0）。
请求示例
curl -X POST https://www.hitheo.ai/api/v1/audio/tts \
-H "Authorization: Bearer $THEO_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"text": "Welcome to Theo. How can I help you today?",
"voice": "theo-voice-warm",
"speed": 1.0
}' \
--output speech.mp3
const audioBuffer = await theo.tts({
text: "Welcome to Theo. How can I help you today?",
voice: "theo-voice-warm",
speed: 1.0,
});
// audioBuffer is an ArrayBuffer — write to file or stream to client
import { writeFileSync } from "fs";
writeFileSync("output.mp3", Buffer.from(audioBuffer));
响应
响应体是原始 MP3 音频字节。| 响应头 | 值 |
|---|---|
Content-Type | audio/mpeg |
Content-Length | 文件大小（字节数） |
X-Request-Id | 唯一请求 ID（前缀为 tts_） |
错误
| 状态码 | 错误码 | 说明 |
|---|---|---|
| 400 | missing_text | 缺少必填的 text 参数 |
| 401 | invalid_api_key | API 密钥缺失或无效 |
| 502 | tts_provider_error | Theo 语音引擎返回错误——请重试 |
| 503 | tts_unavailable | 此实例未配置文字转语音功能 |
