Sounds received by the mic cause the menu to close unexpectedly

The information in this article applies to:

• SpeechKit 2.0, 2.1

Symptoms

When recognition is active and a menu is open, sounds received by the mic cause the menu to close unexpectedly.

Cause

When the speech filtering option is on (e.g., StartRecognition(,,True,,)), any audio detected will cause the any down menu to be raised.

What is happening is on purpose. On the utterance_begin event, the Chant component causes the menu to be raised. This is in case the next recognized speech is a menu title that causes a menu down operation. This will not occur if a menu is already down.

Status

A new feature has been added to SpeechKit 2.1. The AutoMenu flag indicates whether you want the Chant component to automatically raise the menu. This is the recommended behavior.
