Abstract
This invention (10, 50) uses an interface (12, 52) to receive a voice input from a user, and a speech recognition unit (18, 54) coupled to the interface (12, 52) to monitor the voice input and recognize a predetermined set of voice commands from the voice input. The speech recognition unit (18, 54) generates a command signal that corresponds to the recognized voice command, which is received by a controller unit (20, 58). The controller unit (20, 58) activates a speech acquisition unit (16, 56) coupled to the controller unit (20, 58) to collect and stop collecting the voice input in response to a control signal generated by the controller unit (20, 58). a memory (24, 56) is provided to store the collected voice input.
Claims7
A method for hands-free audio memo, comprising the steps of:
- receiving a voice input from a user;
- recognizing a memo start voice command in the voice input indicative of the user's desire to record an audio memo;
- collecting subsequent voice input;
- storing the subsequent voice input;
- recognizing a memo management voice command in the voice input indicative of the user's desire to manage stored voice input;
- and
- performing management functions in response to further voice input.
A method for hands-free audio memo, comprising the steps of:
- receiving a voice input from a user;
- recognizing a memo start voice command in the voice input indicative of the user's desire to record an audio memo;
- collecting subsequent voice input;
- storing the subsequent voice input;
- storing a speech model of digital voice signal inputs corresponding to each of a plurality of voice commands;
- recognizing a voice command in the voice input indicative of a specific function by determining if said voice input matches any speech model corresponding to one of said specific functions;
- and
- following recognition of a voice command indicative of a specific function recognizing subsequent voice commands by attempting to match subsequent voice input to a subset of speech models of digital voice signals corresponding to valid commands following said specific function.
