### Answer I don't have specific troubleshooting documentation for microphone pickup or transcription issues in the available sources. The sources explain that Retell AI uses Automatic Speech Recognition (ASR) to convert spoken language into text [(1) ]() , and that ASR quality is critical for the agent to understand callers . Speech Processing involves real-time technologies including Voice Activity Detection (VAD) to detect when the caller starts and stops speaking [(2) ]() . However, I don't have detailed troubleshooting steps for when the microphone isn't being picked up or transcription isn't working. I'd recommend checking these potentially helpful resources: - [Speech Processing]() - [Automatic Speech Recognition (ASR) ]() You might also want to: - Check browser permissions for microphone access - Verify your internet connection stability - Test with a different browser or device Would you like me to try to provide a general answer based on my knowledge of common voice agent issues?

### Answer Based on the Discord post, there was a recent ASR (Automatic Speech Recognition) error affecting inbound calls [(1) ]() . The Retell AI team acknowledged the issue and posted an incident update at . This timing suggests your audio pickup issue may be related to this system-wide ASR problem rather than a configuration issue on your end. What's likely happening: Voice Activity Detection (VAD) detects when someone is speaking [(2) ]() , and ASR converts that speech into text [(3) ]() . If ASR is experiencing errors, the agent won't transcribe what callers are saying, even if VAD is detecting voice activity [(4) ]() . Recommended steps: 1. Check the [Retell AI status page]() for updates on the ASR incident 2. If the issue persists after the incident is resolved, verify your agent's ASR configuration 3. Test with a fresh call to see if transcription has been restored The team was actively investigating this issue, so it may already be resolved or in progress [(1) ]() .

### Answer I don't have specific troubleshooting documentation for situations where calls are being logged but the agent isn't responding or transcribing audio without showing an explicit ASR error. The sources explain that Speech Processing involves ASR (converting speech to text) and VAD (detecting when someone is speaking) [(1) ]() , and that ASR quality directly impacts the agent's ability to understand callers [(2) ]() . VAD detects when speech occurs and helps the system know when to listen [(3) ]() . However, I don't have detailed troubleshooting steps for this specific scenario where: - Calls are being logged successfully - No explicit "error_asr" appears - The agent isn't picking up or responding to audio Potential areas to investigate: - Check your agent's ASR provider configuration - Verify microphone permissions in the browser/application - Review call logs for any other error indicators - Test with different audio input devices or browsers Check out these potentially useful sources: - [Speech Processing]() - [Automatic Speech Recognition (ASR) ]() - [Voice Activity Detection (VAD) ]() For more detailed technical support with this issue, you may want to: - Visit [Documentation]() - Visit [Hire certified Retell partner]() Would you like me to try to provide a general answer based on my knowledge of common voice agent issues?
