Abstract
Automatic correcting of user's speech impairment in speech may include obtaining the audio signal of a given user's speech, and analyzing the obtained audio signal to identify artifacts caused by the user's impairment. The obtained audio signal may be modified by eliminating the identified artifacts from it. The modified audio signal may be provided, e.g., to be played or broadcast or transmitted.
Claims12
A system for correcting effects of a user's speech impairment, comprising:
- a processor;
- a receiver module operable to obtain audio signal of a speech;
- an analysis module operable execute on the processor and further operable to analyze the audio signal to identify audio signal artifacts caused by the user's speech impairment;
- a modifier module operable to modify the audio signal by eliminating the identified audio signal artifacts from the audio signal;
- a player module operable to provide the modified audio signal;
- and
- a database of impairment-to-artifact associations including repeated instances of phonemes associated with stuttering, inappropriate verbiage inserted into speech associated with Tourete Syndrome, and slurred pronunciation associated with lisping,
- wherein the analysis module is operable to identify the audio signal artifacts caused by the user's speech impairment by employing identified differences between audio signals of the user reading a text with a predefined audio signal associated with the text.
5 more elements
A computer readable storage medium, excluding a signal per se,
- storing a program of instructions executable by a machine to perform a method of correcting effects of a user's speech impairment, the method comprising:
- obtaining audio signal of a speech;
- analyzing, by a processor, the audio signal to identify audio signal artifacts caused by the user's speech impairment;
- modifying, by the processor, the audio signal by eliminating the identified audio signal artifacts from the audio signal;
- providing the modified audio signal;
- and
- accessing a database of impairment-to-artifact associations, wherein the database including repeated instances of phonemes associated with stuttering, inappropriate verbiage inserted into speech associated with Tourete Syndrome, and slurred pronunciation associated with lisping,
- wherein the analyzing further comprises identifying the audio signal artifacts caused by the user's speech impairment by employing identified differences between audio signals of the user reading a text with a predefined audio signal associated with the text.
