Abstract

An information processing apparatus whereby advice having appropriate content can be given at an appropriate timing with regard to a method of user utterance, thereby making it possible to reduce the probability of misrecognition due to the method of utterance. An execution unit executes processing that conforms to the result of speech recognition. An analyzing unit analyzes the suitability of input speech for the speech recognition. A cancel instruction unit inputs an instruction to cancel the processing that has been executed by the execution unit. In response to the cancel instruction, a notification unit notifies the user of guidance related to speech input, based upon the result of the analysis unit.

Claims

1. An information processing apparatus comprising:

at least one processor programmed to control;

an analysis unit configured to analyze the suitability of input speech for speech recognition;

a speech recognition unit configured to perform the speech recognition to the input speech;

a display control unit configured to display a result of the speech recognition on a display unit;

an acceptance unit configured to accept a user'"'"'s operation for canceling the display of the result of the speech recognition; and

an output unit configured to output a guidance message relating to the input speech based upon result of analysis by said analysis unit if the user'"'"'s operation is accepted by said acceptance unit.

2. The apparatus according to claim 1, further comprising a storage unit configured to store, according to a category of the suitability, a frequency at which the user'"'"'s operation has been accepted;

wherein said output unit outputs the guidance message if the frequency exceeds a predetermined value.

3. An information processing method comprising:

using at least one processor to perform the following;

analyzing the suitability of input speech for speech recognition;

performing the speech recognition to the input speech;

displaying a result of the speech recognition on a display unit;

accepting a user'"'"'s operation for canceling the display of the result of the speech recognition; and

outputting a guidance message relating to the input speech based upon the analysis result if the user'"'"'s operation is accepted.

4. A non-transitory computer-readable storage medium having stored thereon a computer program, said program comprising code for performing the following steps:

analyzing the suitability of input speech for speech recognition;

performing the speech recognition to input speech;

displaying a result of the speech recognition on a display unit;

accepting a user'"'"'s operation for canceling the display of the result of the speech recognition; and

outputting a guidance message relating to the input speech based upon the analysis result if the user'"'"'s operation is accepted.
