# 13335: Gather: speechTimeout auto cannot be used with model default

Log Type: APPLICATION

Log Level: WARNING

## Description

Use a positive integer for `speechTimeout` whenever you set `speechModel` on `<Gather>`. Twilio does not support `speechTimeout="auto"` in this configuration, and this warning is raised when that combination is sent.

### Possible causes

* You set `speechTimeout="auto"` on `<Gather>`.
* You also set `speechModel`, and Twilio requires `speechTimeout` to be a positive integer when a speech model is configured.

### Possible solutions

* Change `speechTimeout` to a positive integer value.
* Review the `<Gather>` speech configuration before you deploy it so the `speechModel` and `speechTimeout` values are compatible.
