Abstract

A voice control method is applied in an electronic device. The electronic device includes a voice input unit, a play unit, and a storage unit storing a conversation database and an association table between different ranges of voice characteristics and styles of response voice. The method includes the following steps. Obtaining voice signals input via the voice input unit. Determining which content is input according to the obtained voice signals. Searching in the conversation database to find a response corresponding to the input content. Analyzing voice characteristics of the obtained voice signals. Comparing the voice characteristics of the obtained voice signals with the pre-stored ranges. Selecting the associated response voice. Finally, outputting the found response using the associated response voice via the play unit.

Claims

1. An electronic device comprising:

a voice input unit;

a play unit;

a storage unit storing a plurality of modules, a conversation database of responses each corresponding to a content of voice signals, and an association table between different ranges of voice characteristics and styles of response voice, each range of voice characteristics being associated with a particular style of response voice; and

a processor to execute the plurality of modules,

wherein the plurality of modules comprises;

an obtaining module to obtain voice signals input via the voice input unit;

a response determining module to determine which content is input according to the obtained voice signals, and search in the conversation database to find a response corresponding to the input content;

a voice analyzing module to analyze voice characteristics of the obtained voice signals, compare the voice characteristics of the obtained voice signals with the pre-stored ranges, and select the associated response voice; and

an output control module to output the found response using the associated response voice via the play unit.

2. The electronic device of claim 1, wherein the voice characteristics comprise voice pitch, voice intensity, and speed of speech of the voice of the obtained voice signals.

3. The electronic device of claim 2, wherein the associated response voice has different voice pitch, same voice intensity, and same speed of speech with respect to the input voice signals.

4. A voice control method applied in an electronic device, the electronic device comprising a voice input unit, a play unit, and a storage unit storing a conversation database of responses each corresponding to a content of voice signals, and an association table between different ranges of voice characteristics and styles of response voice, each range of voice characteristics being associated with a particular style of response voice, the method comprising:

obtaining voice signals input via the voice input unit;

determining which content is input according to the obtained voice signals;

searching in the conversation database to find a response corresponding to the input content;

analyzing voice characteristics of the obtained voice signals;

comparing the voice characteristics of the obtained voice signals with the pre-stored ranges and selecting the associated response voice; and

outputting the found response using the associated response voice via the play unit.

5. The voice control method of claim 4, wherein the voice characteristics comprise voice pitch, voice intensity, and speed of speech of the voice of the obtained voice signals.

6. The voice control method of claim 4, wherein the associated response voice has different voice pitch, same voice intensity, and same speed of speech with respect to the input voice signals.
