1. A speech input device comprising:
- a first sound pick-up unit configured to pick up a sound and outputting a first speech waveform signal based on the picked up sound;
a speech-segment determination unit configured to detect a speech segment corresponding to a voice input period during which a voice is input or a non-speech segment corresponding to a non-voice input period during which no voice is input, based on the first speech waveform signal and to output a determination signal that indicates whether the picked up sound is the speech segment or the non-speech segment; and
an indicating unit configured to indicate a detected state of the speech segment based on the determination signal.

Abstract
A sound is picked up by a microphone. A speech waveform signal is generated based on the picked up sound. A speech segment or a non-speech segment is detected based on the speech waveform signal. The speech segment corresponds to a voice input period during which a voice is input. The non-speech segment corresponds to a non-voice input period during which no voice is input. A determination signal is generated that indicates whether the picked up sound is the speech segment or the non-speech segment. A detected state of the speech segment is indicated based on the determination signal.

12. A speech input method comprising the steps of:
-
picking up a sound; generating a first speech waveform signal based on the picked up sound; detecting a speech segment corresponding to a voice input period during which a voice is input or a non-speech segment corresponding to a non-voice input period during which no voice is input, based on the first waveform signal; generating a determination signal that indicates whether the picked up sound is the speech segment or the non-speech segment; and indicating a detected state of the speech segment based on the determination signal. - View Dependent Claims (13, 14)

15. A speech input program stored in a non-transitory computer readable storage medium, comprising:
-
a program code of picking up a sound; a program code of generating a first speech waveform signal based on the picked up sound; a program code of detecting a speech segment corresponding to a voice input period during which a voice is input or a non-speech segment corresponding to a non-voice input period during which no voice is input, based on the first speech waveform signal; a program code of generating a determination signal that indicates whether the picked up sound is the speech segment or the non-speech segment; and a program code of indicating a detected state of the speech segment based on the determination signal. - View Dependent Claims (16, 17)

18. A communication apparatus comprising:
-
a first sound pick-up unit configured to pick up a sound and outputting a speech waveform signal; a transmission unit configured to transmit the speech waveform signal; a speech-segment determination unit configured to detect a speech segment corresponding to a voice input period during which a voice is input or a non-speech segment corresponding to a non-voice input period during which no voice is input, based on the speech waveform signal and to output a determination signal that indicates whether the picked up sound is the speech segment or the non-speech segment; and an indicating unit configured to indicate a detected state of the speech segment based on the determination signal. - View Dependent Claims (19, 20)
