Abstract
Various embodiments provide a method and apparatus for providing a silent speech solution which allows the user to speak over an electronic media such as a cell phone without making any noise. In particular, measuring the shape of the vocal tract allows creation of synthesized speech without requiring noise produced by the vocal chords.
Claims18
An apparatus for providing silent speech, the apparatus comprising:
- a data storage;
- and
- a processor communicatively connected to the data storage, the processor being configured to:
- output an output signal;
- receive an impulse response associated with the output signal;
- determine a vocal tract impedance profile based on the impulse response;
- create a speech signal based on the vocal tract impedance profile;
- and
- output the speech signal.
A system for providing silent speech, the system comprising:
- a silent speech controller;
- a pulse output communicatively connected to the silent speech controller;
- a response input communicatively connected to the silent speech controller;
- and
- a target device communicatively connected to the silent speech controller;
- wherein the silent speech controller is configured to:
- output an output signal to the pulse output;
- receive an impulse response associated with the output signal from the response input;
- determine a vocal tract impedance profile based on the impulse response;
- create a speech signal based on the vocal tract impedance profile;
- and
- output the speech signal to the target device;
- and
- the target device is configured to:
- output an audio signal based on the speech signal.
A method for providing silent speech, the method comprising:
- at a processor communicatively connected to a data storage, outputting an output signal;
- receiving, by the processor in cooperation with the data storage, an impulse response associated with the output signal;
- determining, by the processor in cooperation with the data storage, a vocal tract impedance profile based on the impulse response;
- creating, by the processor in cooperation with the data storage, a speech signal based on the vocal tract impedance profile;
- and
- outputting, by the processor in cooperation with the data storage, the speech signal.
A computer-readable storage medium storing instructions which, when executed by a computer, cause the computer to perform a method, the method comprising:
- outputting an output signal;
- receiving an impulse response associated with the output signal;
- determining a vocal tract impedance profile based on the impulse response;
- creating a speech signal based on the vocal tract impedance profile;
- and
- outputting the speech signal.
