I am facing the issue of distorted voice, In some of my calls. The voice sounds distorted sometimes when the user is called, sometimes the voice is clear. 11Labs VoiceID: 625jGFaa0zTLtQfxwc6Q, model eleven_flash_v2_5 LLM model: GPT 4.1 I don't know what's causing this issue, but as I am already in production phase it's a major bottleneck stoping me from scaling.

Hi there, Thank you for your message. Our team is currently out of the office. We operate Monday through Friday, from 9:00 AM to 8:00 PM Pacific Standard Time (PST). We’ll get back to you as soon as possible during our normal business hours. If your message is urgent, please mark it accordingly or include “URGENT” in the subject line, and we’ll do our best to respond promptly. Warm regards, Vapi Customer Support Team

Actionable Step: Start by reviewing your recent calls in the Vapi dashboard's Call Logs. Compare a call where the voice was distorted to one where it was clear—look for differences in error messages, call duration, or tool execution results. Navigate to:

Observe > Call Logs

This will help you pinpoint patterns and gather the Call ID and timestamp for further support or deeper troubleshooting if needed. For more details, see the [Vapi debugging guide](https://docs.vapi.ai/debugging). Source: - [Debugging voice agents](https://docs.vapi.ai/debugging)

Hey, I know how stressful this is in production, especially when audio quality is inconsistent. This usually comes from sample rate mismatches, streaming buffers, or network jitter with real-time TTS like Eleven Flash. I’ve helped debug this exact issue in VAPI stacks before and can help you isolate it fast. Quick question: are you using streaming audio or full audio payloads, and what codec/sample rate is your call layer expecting? @Rush

@Kizzz I tried doing that but it didn't work for me, @Jarrah How do i check that if i am using streaming or full audio and what sample rate the call layer is expecting

Hey Rush, please share the vapi's call ID so we can debug.
