Method for enabling Automatic Push to Activate (APTA) listening mode for hands free speech applications

Many speech applications in embedded devices require the hands free operation. Given that, the user wants to use the Listening/Record button as little as possible. One solution is to use an Always Listen Mode, but this technology is not always feasible in embedded devices. We use the PTA (Push to Activate) mode so that the user can be prompted when to speak and then the system will automatically detect the end of speech. Normally the user would have to press the Listening/Record button to start speaking but in this case the system would do a virtual press of the button once the prompting for the speech input of the application is complete.

This invention provides a pseudo-listening mode that minimizes the requirement to use the Listening/Record button on platforms where Alway Listening is not available. The advantage is that the user of the speech application will have both hands free to do their work. Depending on the environment, the user may not be able to touch the device that is being for the speech application. Examples of this would be in warehouse environments, inventory management, order entry systems, etc., where the user needs to interact with the speech application / entry system hands free.

In traditional PTA listening mode the system prompts the user for an input and the user has to press the listening/record button in order to instruct the system...
