Monitoring and activating speech process in response to a trigger phrase
First Claim
1. A method of processing received data representing speech comprising the steps of:
- monitoring the received data to detect the presence of data representing a first portion of a trigger phrase in said received data;
sending, on detection of said data representing the first portion of the trigger phrase, a control signal to activate a speech processing block,monitoring the received data to detect the presence of data representing a second portion of the trigger phrase in said received data, and further comprising, if said control signal to activate the speech processing block has previously been sent;
if the data representing the second portion of the trigger phrase is not detected, sending a deactivation command to deactivate the speech processing block; and
if said data representing the second portion of the trigger phrase is detected, maintaining the activation of said speech processing block;
after detecting the data representing the first portion of the trigger phrase;
supplying a part of the received data to an adaptive speech enhancement block, andtraining the speech enhancement block to derive adapted parameters for the speech enhancement block; and
if the data representing the first portion of the trigger phrase is detected;
supplying at least a part of the received data to the speech enhancement block, operating with the adapted parameters, andoutputting enhanced data from the speech enhancement block.

Abstract
A method of processing received data representing speech comprises monitoring the received data to detect the presence of data representing a first portion of a trigger phrase in said received data. On detection of the data representing the first portion of the trigger phrase, a control signal is sent to activate a speech processing block. The received data is monitored to detect the presence of data representing a second portion of the trigger phrase in said received data. If the control signal to activate the speech processing block has previously been sent, then, on detection of the data representing the second portion of the trigger phrase, the activation of the speech processing block is maintained.
