Hello, could someone who has experienced the latest updates of Vapi (in the last 3 months) help me set up the best settings for a French voice that handles reservations? I’ve set everything up, but sometimes there are comprehension issues, especially when taking a reservation, and the response times are a bit too long.

Hi there! 👋 I'd be happy to help you optimize your Vapi settings for a French reservation voice! I don't have specific information about the exact best settings for your particular French voice reservation system, as that would depend on your specific implementation. However, I can definitely help with optimizing your Vapi settings to address both the comprehension issues and response times you're experiencing. ## Recent Updates That Might Help There have been several relevant updates to Vapi in the last few months that could help with your French voice: - **Voice Fallback Plan**: You can now define a fallback plan in your assistant's voice settings to specify alternative voices if your primary voice provider fails ([Vapi Changelog](https://docs.vapi.ai/changelog/2024/11/21)). - **Multilingual Support in Tool Messages**: You can now use the 
contents
property in various tool messages to provide message variants for different languages ([Vapi Changelog](https://docs.vapi.ai/changelog/2024/10/25)). - **Automatic Translation**: Vapi automatically translates the first item to the active language by default for several message types if specific content isn't provided for a language ([Vapi Changelog](https://docs.vapi.ai/changelog/2024/10/25)). - **Language Selection for PlayHTVoice**: The 
language
property has been added to 
PlayHTVoice
, allowing you to specify the desired language for speech synthesis ([Vapi Changelog](https://docs.vapi.ai/changelog/2024/11/24)). ## Improving Comprehension For the comprehension issues you're experiencing, consider these settings: 1. **Transcriber Selection**: Make sure you're using a transcriber that properly supports French. According to the documentation, "Vapi's multilingual support is facilitated through transcribers like Deepgram and Talkscriber, each supporting different languages and models" ([Vapi Multilingual Documentation](https://docs.vapi.ai/customization/multilingual)).
2. **Word Boosting**: Ensure that word boosting is consistently applied across all transcription processes, especially for reservation-specific terms ([Discord Discussion](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336366437773738150)). 3. **SSML**: Enable SSML in your voice settings for better pronunciation control, which is especially important for French. To enable SSML in VAPI, log in to your account, navigate to voice settings, enable the SSML option, and save changes ([Discord Discussion](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1296031572956549171)). 4. **Voice Activity Detection (VAD)**: Calibrate your VAD settings to avoid truncated recordings that can hinder speech comprehension ([Discord Discussion](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1316042862630146058)). ## Reducing Response Times For the long response times: 1. **Review Configuration Settings**: Check settings like 
silenceTimeoutSeconds
, 
responseDelaySeconds
, and 
llmRequestDelaySeconds
that might affect call setup and response times ([Discord Discussion](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1332286268805087272)). 2. **Adjust Conversation Flow Settings**: Modify 
numWordsToInterruptAssistant
(controls how long the person speaks before the AI responds) and 
maxDurationSeconds
(defines how long the AI waits for a response before proceeding) ([Discord Discussion](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1334027136305991750)). 3. **Network Optimization**: Optimize your network path, server configuration, and code efficiency. Consider using efficient protocols like WebRTC or WebSocket ([Discord Discussion](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336685825227755591)).
4. **Chunk Plan Setting**: For French voices, make sure 
chunkPlan.enabled
is properly configured. Using 
chunkPlan.enabled
for non-English languages and tuning 
minCharacters
and 
punctuationBoundaries
can help with response times ([Discord Discussion](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1343543475383046185)). Is there a specific aspect of these settings you'd like me to elaborate on further?
