Non-Streaming Response

{
  "data": {
    "audio": "hex-encoded audio data...",
    "status": 2
  },
  "extra_info": {
    "audio_length": 3500,
    "audio_sample_rate": 32000,
    "audio_size": 56000,
    "bitrate": 128000,
    "audio_format": "mp3",
    "audio_channel": 1,
    "word_count": 24,
    "usage_characters": 30
  },
  "base_resp": {"status_code": 0, "status_msg": "success"}
}

data.audio is hex-encoded. Decode: bytes.fromhex(audio_hex)

SSE Streaming Response

Each chunk: data: {"data":{"audio":"hex...","status":1},...}

Final chunk has status: 2 and includes extra_info.

非流式响应

{
  "data": {"audio": "hex编码音频...", "status": 2},
  "extra_info": {
    "audio_length": 3500,
    "audio_sample_rate": 32000,
    "audio_size": 56000,
    "audio_format": "mp3",
    "word_count": 24,
    "usage_characters": 30
  },
  "base_resp": {"status_code": 0, "status_msg": "success"}
}

data.audio 为 hex 编码，解码：bytes.fromhex(audio_hex)

SSE 流式响应

每个数据块：data: {"data":{"audio":"hex...","status":1},...}

最后一个 chunk status: 2，包含完整 extra_info。
