Combined speech recongnition and text-to-speech generation

A computing device for performing large vocabulary speech recognition comprising:

• computer readable memory;
• one or more processors capable of executing program instructions read from said memory;
• a microphone or audio input for providing an electronic signal representing an utterance to be recognized;
• a speaker or audio output for enabling an electronic representation of sound produced in said device to be transduced into a corresponding sound;
• and
• programming recorded in the memory including instructions for:
• performing large vocabulary speech recognition upon an electronic representations of utterances received from the microphone or audio input, including responding to certain utterances as text words which are supplied to a text output and responding to other utterances as a recognized commands;
• providing TTS output to said speaker or audio output saying one or more words of said text output;
• and
• providing TTS or recorded audio output to said speaker or audio output saying the name of a recognized command.

• and
• programming recorded in the memory including instructions for:
• performing large vocabulary speech recognition that responds to the electronic representations of each of a sequence of one or more utterances received from the microphone or audio input by:
• selecting as a best scoring recognition candidate the one or more words recognized by the speech recognition as corresponding to the utterance;
• detecting the end of the utterance;
• and then
• responding to the detection of the end of utterance by providing TTS output to said speaker or audio output saying the one or more words of said best scoring recognition candidate for the utterance;
• whereby the device can generate audio feedback on the one or more words recognized for each of a succession of large vocabulary speech utterances at the end of each such utterance.

• and
• programming recorded in the memory including instructions for:
• performing larger vocabulary speech recognition upon an electronic representation of utterances received from the microphone or audio input to produce a text output;
• responding to text navigation commands by moving a cursor backward and forward in the one or more words of said text output;
• and
• responding to each movement in response to one of said navigational commands by providing a TTS output to said speaker or audio output saying one or more words either starting or ending with the location of the cursor after each of said movements.

• programming recorded in the memory including instructions for:
• performing large vocabulary speech recognition upon an electronic representations of uttered words received from the microphone or audio input to produce a choice list of recognition candidates, each comprised of a sequence of one or more words, selected by the recognition as scoring best against said uttered sound;
• using text-to-speech technology to provide spoken output to said speaker or audio output saying a plurality of the recognition candidates in the choice list;
• enabling the user to select one recognition candidates from among the plurality of such candidates said by said text-to-speech technology.
