First Claim
Patent Images
1. A method of automatically adjusting volume of speech generated by a text-to-speech application comprising the steps of:
- receiving an audio output signal from a text-to-speech application;
responsive to receiving the signal, a volume control system measuring an ambient noise level of an audio environment, wherein the volume control system is separately implemented from the text-to-speech application;
the volume control system calculating a target volume for speech output generated by a text-to-speech application based in part upon said ambient noise level; and
,the volume control system 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, wherein said automatic adjustments occur responsive to a volume control system receiving an audio output signal from the text-to-speech application wherein the volume control system includes said calculation engine, and wherein said volume control system is separately implemented from the text-to-speech application.
