03/23/2025, 2:01 AMHello, how can I solve inconsistent voice volume? HAve a listen to this recording: https://storage.vapi.ai/57cd1534-f651-4547-83cc-0dc612a7dd5f-1742694508122-d83091f6-1b33-4dfd-9c1d-1678fa190f82-mono.wav
in it you can hear the AI talking soft and loud. sometimes it goes really so soft, that you can hardly hear him. He whispers.
Any way to solve this issue?

03/23/2025, 2:02 AMHi there! 👋
I'm unable to listen to your specific recording, but I can definitely help with the inconsistent voice volume issue you're experiencing where the AI sometimes speaks softly or whispers.
Based on the information I have, there are several potential causes and solutions for inconsistent voice volume in AI voice agents:
## Possible Causes
1. **Voice Model Issues**: Some voice models can sound too loud or energetic in certain contexts, while too soft in others. According to [user reports](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1341976720009592914), this can lead to volume inconsistencies.
2. **Configuration Settings**: Incorrect VAPI settings like voiceId and speed can cause audio output problems, including volume inconsistencies. [User discussions](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1330872643037167626) indicate that high style property values can lead to unpredictable behavior.
3. **Voice Activity Detection (VAD) Settings**: Improper VAD settings can cause truncated recordings or missed speech, which might be perceived as volume inconsistency. [Documentation](https://docs.vapi.ai/customization/speech-configuration) shows that sensitivity and threshold settings can impact how well the AI captures speech.
## Solutions to Try
1. **Adjust Voice Settings**: Check and adjust your VAPI settings, including voiceId, speed, and volume parameters. For 11Labs specifically, you can tweak parameters like style, streamingLatency, and boosting to improve consistency, as mentioned in [community discussions](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336706862518636635).

03/23/2025, 2:02 AM2. **Try Different Voice Models**: Experiment with different voice models or switch to a more stable voice provider. Some users have found success by changing the voice model architecture, according to [community feedback](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1339794428688076871).
3. **Improve Audio Quality**: Ensure you're using high-quality audio inputs and consider noise reduction techniques. [Best practices](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336377512233664523) suggest that clear audio input is crucial for consistent AI voice output.
4. **Check Network Stability**: Maintain a stable network connection, as network issues can lead to voice distortion and inconsistent volume, as noted in [troubleshooting guides](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336377512233664523).
5. **Adjust Emotional Prompting**: Use emotional prompting to shape the AI's tone, which can help maintain more consistent volume levels, as suggested in the [prompting guide](https://docs.vapi.ai/prompting-guide).
Would you like more specific guidance on any of these solutions, or do you have any other questions about your AI voice agent?
