Hi Markus! 😊 I understand how frustrating it can be when audio files and transcriptions don't match the actual call duration. Based on the information you've provided, there are a few common causes for this issue in Vapi's transcription service:
1. **Voice Activity Detection (VAD) Settings**: If VAD is not calibrated correctly, it may miss parts of the conversation, leading to truncated recordings. Adjusting these settings can help capture speech more accurately.
2. **Audio Channel Mixing Issues**: If the agent and customer are recorded on the same channel, overlapping speech can occur, which might result in parts of the conversation being cut off.
3. **Endpointing Issues**: If the endpointing settings are not configured properly, the system might prematurely determine that a speaker has finished talking, cutting off ongoing speech.
4. **Background Noise and Poor Audio Quality**: These factors can also affect transcription accuracy, leading to discrepancies in the recorded audio.
To troubleshoot, I recommend checking the VAD settings to ensure they are optimized, verifying that audio channels are separated for clarity, and reviewing the endpointing configurations. If the problem persists, it might be helpful to consult Vapi support with specific call IDs for further assistance.
Let me know if you need any more help! 📞
