Technical details
Endpoint
POSThttps://dt0ur.online/api/speech/transcribe?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to convert a WAV audio file hosted at a public URL into English text with timestamps, especially in automated pipelines where Whisper-quality transcription is required. Prefer it for single-file transcription tasks where the audio is already in WAV/PCM format. Avoid for non-WAV formats.
Side effects
- Non-WAV formats (MP3, OGG, FLAC) cause 500 errors — only PCM WAV is supported
- Inaccessible or private audio URLs result in failure to fetch the file
- Very long audio files may time out or exceed processing limits
- Audio with heavy background noise or non-English speech may produce inaccurate transcriptions
- Malformed or corrupt WAV files cause decoding errors
