Method and device to distinguish between voice conversation and automated speech recognition
View Patent ↗A method and device for performing some preprocessing on voice transmissions depending upon the intended destination of the transmission. The device includes a receiving component configured to receive a voice signal from a source over a network. The device also includes a processing component configured to determine a destination address associated with the received signal, determine a signal processing algorithm from a plurality of signal processing algorithms based on the determined address, and process the voice signal according to the specified algorithm. The device further includes a delivery component configured to send the processed signal to the associated address.
1. A method comprising:
preprocessing a received signal according to a transmission destination of the received signal to determine a signal path to the transmission destination from a user input unit;
determining a processing algorithm from a plurality of signal processing algorithms including algorithms to assist speech recognition based on the transmission destination;
processing the received signal according to the determined algorithm; and
sending the processed signal to the transmission destination from the user input unit.
2. The method of claim 1 , wherein determining the processing algorithm comprises matching a database lookup table entry and a signal processing algorithm, such that the signal processing algorithm is configured to improve the processed signal for the determined transmission destination.
3. The method of claim 1 , further comprising:
determining the originator of the received signal, if the determined transmission destination is a human recipient; and
if the determined originator is a computer-based system, alerting the recipient that the voice signal is from a computer-based system.
4. A method comprising:
sending a signal from a user input source to a transmission destination according to an address associated with a generated phonation and preprocessing the signal to generate a change signal; and
if the transmission destination is a speech recognition server, sending the change signal from the transmission destination to the user input source, determining a signal path, generating a phonation for reception by a speech recognition server, and sending the newly processed phonation, otherwise generating a phonation at the user input source for reception by a human recipient.
5. A computer-based device comprising:
a first component configured to process a phonation at a user input source for reception by a human recipient;
a second component configured to send the processed phonation to a transmission destination according to an address associated with the phonation on a determined signal path;
a third component configured to receive a change signal from the transmission destination; and
a fourth component configured to process a next phonation for reception by a speech recognition server according to a received change signal, and send the newly processed phonation to the transmission destination on the signal path.
6. An apparatus comprising:
means for processing a phonation at a user input source for reception by a human recipient;
means for sending the processed phonation to a transmission destination according to an address associated with the phonation on a determined signal path; and
if the destination is a speech recognition server, means for sending a change signal from the transmission destination to the user input source, means for processing a next phonation for reception by a speech recognition server, and means for sending the newly processed phonation on the signal path.
