04/30/2025, 6:08 PMHi team @Vapi @Vapi Support Bot ,
I am facing an issue with the VAPI Web SDK where the assistant starts speaking a tool call response but abruptly stops mid-sentence. The full response is received, but only part of it is spoken. This is affecting user experience and trust in the assistant.
You can refer to this specific case using Call ID:
7951cdd1-760e-4be9-bac7-77c1a868bb5cv

04/30/2025, 6:10 PMTry adjusting your API settings to prevent speech cut-offs during tool call responses:
Copy code
javascript
// Update these parameters in your VAPI configuration
const vapiConfig = {
numWordsToInterruptAssistant: 5, // Increase this value
maxDurationSeconds: 10 // Increase this value
};v

04/30/2025, 8:22 PMHey! To help track down this issue, could you share:
- When exactly this happened (the timestamp)
- What response you expected to get
- What response you actually got instead
This would really help us figure out what went wrong!

05/01/2025, 10:27 PMWhat is your expected result if the assistant is able to speak the full sentence? Is the user saying a string value like "Password expired" or are they using dial tones to choose an option? Also, please provide a screenshot or code snippet of the tool "process_user_request" so I can get a better understanding of how the tool is being used.

05/05/2025, 7:31 PMI see there is a couple of issues:
1. If you filled out the message for request-complete, it will override what is spoken in the toolCallResult. I suggest clearing the message from request-complete.
2. The toolCallResult needs to be one line in order to get consistent results. Multi-line results will be unstable. Please follow this documentation and let us know the results of the changes.

05/06/2025, 8:35 AMIn the doc its mentioned
result (Y): This field holds the actual output or result of your tool’s execution. The format and content of “result” will vary depending on the specific function of your tool. It could be a string, a number, an object, an array, or any other data structure that is relevant to the tool’s purpose.c
