音频格式与语言
Shisa ASR 接受多种常见格式的 base64 编码音频，并跨97种语言自动识别所说的语言。本页列出支持的格式，演示如何将音频编码为 base64，并介绍语言检测。
支持的音频格式
将原始的 base64 编码音频数据传入 audio 字段。服务器会从二进制头自动检测格式——您无需自行声明格式。
| Format | MIME type | Detection |
|---|---|---|
| WAV | audio/wav | RIFF header |
| OGG | audio/ogg | OggS header |
| MP3 | audio/mpeg | ID3 tag or MPEG sync bytes |
| FLAC | audio/flac | fLaC header |
将音频编码为 base64
将任何受支持的文件转换为 base64，然后将其直接嵌入您的请求中:
# Encode any supported format to base64
base64 -w0 audio.ogg # Linux
base64 -i audio.ogg # macOS
# Use in a curl request
curl -s -XPOST 'https://api.shisa.ai/asr/srt/audio_llm' \
-H 'Authorization: Bearer YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{ "audio": "'$(base64 -w0 audio.ogg)'" }'
语言检测（LID）
API 支持跨97种语言的自动语言识别（LID）。当您省略 language 参数时，所说的语言会被自动检测，并在响应的 language 字段中返回。要强制使用特定语言，请显式设置 language（例如 "ja" 或 "en"）。
