First Claim
Patent Images
1. A method of automatically adjusting volume of speech generated by a text-to-speech application comprising the steps of:
- measuring an ambient noise level of an audio environment;
calculating a target volume for speech output generated by a text-to-speech application based in part upon said ambient noise level; and
, automatically adjusting volume of speech generated by said text-to-speech application responsive to said calculating step.

Abstract
A method of automatically adjusting volume of speech generated by a text-to-speech application can include measuring an ambient noise level of an audio environment. A target volume for speech output generated by a text-to-speech application can be calculated based in part upon the ambient noise level. A volume of speech generated by the text-to-speech application can be automatically adjusted responsive to the performed calculation.

10. A system for automatically adjusting a volume of speech generated by a text-to-speech application comprising:
-
a receiving transducer configured to detect an ambient noise level;
a text-to-speech application;
a calculation engine configured to calculate a target volume based in part upon said ambient noise level; and
,an audio transducer configured to play speech generated by said text-to-speech application, wherein an output level of said speech is automatically adjusted based upon said target volume.
