Abstract: To ensure optimization of a voice output timing. A voice synthesis apparatus that performs voice synthesis based on a statistical acoustic model includes a processor that executes a program and a storage device that stores the program. The voice synthesis apparatus performs a selection process and a synthesis process. The selection process selects a synthesis method applied to an input voice among a plurality of synthesis methods in combination of sizes of the statistical acoustic models with voice synthesis processes based on the input voice. The synthesis process synthesizes the input voice by the synthesis method selected in the selection process.

Abstract: In a speech signal processing device including a plurality of devices and a speech signal processing device, a first device of the devices is connected to a microphone to output a microphone input signal to the speech signal processing device. A second device of the devices is connected to a speaker to output a speaker output signal, which is the same as the signal output to the speaker, to the speech signal processing device. The speech signal processing device synchronizes a waveform included in the microphone input signal with a waveform included in the speaker output signal, and removes the waveform included in the speaker output signal from the waveform included in the microphone input signal.

Abstract: Systems and methods for determining mean opinion scores (MOS) for variable bit rate (VBR) audio streams transmitted over VoIP networks are described. In an embodiment, a method may include monitoring a communication over a network and detecting portions of the communication including packets having a different packet payload sizes. The method may also include deriving bit rates corresponding to those portions. The method may then include calculating MOS values for each portion based on the derived bit rates, and calculating an overall MOS value for the communication based upon each individual MOS value averaged according to a distribution of packets having the different packet payload sizes.

Abstract: Included in a speech synthesizer, a natural language processing unit divides text data, input from a text input unit, into a plurality of components (particularly, words). An importance prediction unit estimates an importance level of each component according to the degree of how much each component contributes to understanding when a listener hears synthesized speech. Then, the speech synthesizer determines a processing load based on the device state when executing synthesis processing and the importance level. Included in the speech synthesizer, a synthesizing control unit and a wave generation unit reduce the processing time for a phoneme with a low importance level by curtailing its processing load (relatively degrading its sound quality), allocate a part of the processing time, made available by this reduction, to the processing time of a phoneme with a high importance level, and generates synthesized speech in which important words are easily audible.
