Abstract
A voice processing device includes a voice pitch converting unit that performs a voice pitch converting process with respect to an input voice signal and converts voice pitch of the input voice signal, an error detecting unit that detects an error between the number of samples of an output voice signal, which is expected, and the number of samples of the output voice signal, which is actually output, and a time length control unit that controls adjustment of the time length in such a manner that the time length of the output voice signal is corrected by the amount of the error.
Claims9
A voice processing device, comprising:
- a voice pitch converting unit that performs a voice pitch converting process with respect to an input voice signal and converts voice pitch of the input voice signal;
- an error detecting unit that detects an error between the number of samples of an output voice signal, which is expected, and the number of samples of the output voice signal, which is actually output;
- and
- a time length control unit that controls an adjustment of a time length in such a manner that the time length of the output voice signal is corrected by the amount of the error.
A voice processing method of a voice processing device including a voice pitch converting unit that performs a voice pitch converting process with respect to an input voice signal and converts voice pitch of the input voice signal, an error detecting unit that detects an error between the number of samples of an output voice signal, which is expected, and the number of samples of the output voice signal, which is actually output, and a time length control unit that controls an adjustment of a time length in such a manner that the time length of the output voice signal is corrected by the amount of the error, the method comprising:
- allowing the voice pitch converting unit to perform the voice pitch converting process with respect to the input voice signal;
- allowing the error detecting unit to detect the error;
- and
- allowing the time length control unit to control the adjustment of the time length.
A program causing a computer to execute a process including:
- performing a voice pitch converting process with respect to an input voice signal and converting voice pitch of the input voice signal;
- detecting an error between the number of samples of an output voice signal, which is expected, and the number of samples of the output voice signal, which is actually output;
- and
- controlling an adjustment of a time length in such a manner that the time length of the output voice signal is corrected by the amount of the error.
