The background signal is subtracted from the voice signal through acoustic wave destruction.
A source signal (e.g. a voice test) is processed by a voice coder (1) or transmitted and converted into a receive signal (coded voice signal).
The voice input unit receives a voice signal from the user, converts the received voice signal into an electric signal, and outputs the converted electric signal.
Whether the spectrum vector represents a voice signal or a non-voice signal is detected.
The voice recorder system amplifies and records a low-level voice signal of a called party, such that the recorded voice signal is normally reproduced, and the user easily listens to the reproduced voice signal.
In this device, the speech/speechless judgment unit (102) outputs the degree of speech of an input speech signal (called a speech degree) to the animation creation unit (103).
In accordance with the invention, a discrete time speech signal is encoded by identifying a speech element in the speech signal.
Wideband speech is synthesised from a bandlimited speech signal, for example from speech which has been transmitted via the public switched telephone network.
A common narrow-band speech signal is expanded into a wide-band speech signal.
Such directionality may serve to amplify a desired speech signal in the first signal and attenuate the desired speech signal from the second signal.
In doing so, a frequency domain representation of a test speech signal and a reference speech signal are generated.
The expanded speech signal gives the impression of a wide-band speech signal regardless of what type of vocoder is used.
Error calculating means (15) calculates the error (En) between the speech signal (Sn) and the reproduction coded speech signal (Sna).
The source speech signal is encoded into samples of encoding parameters, wherein the encoding comprises the step of segmenting the source speech signal into segments based on characteristics of the source speech signal.
Initially, the speech converter receives a formants signal representing an input speech signal and a pitch signal representing the input signal's fundamental frequency.
The speech signal is represented by a residual signal generated by filtering the speech signal with a Linear Predictive Coding (LPC) analysis filter.
Analysis by synthesis calculates a difference by subtracting (130) synthesized speech from input speech.
A method of coding a sampled speech signal in which the speech signal is divided into sequential frames.
A digital speech signal is received (200).
Otherwise, the frame is likely to contain a non-stationary speech segment such as a voiced onset or rapidly evolving voiced speech signal.
This invention relates to a framework for converting a source speech signal associated with a source voice into a target speech signal that is a representation of the source speech signal associated with a target voice.
A detected speech signal (34) is generated based on both at least one extracted speech signal (28) and on at least one extracted noise signal (30).
When the input speech signal is detected during presentation of the output audio signal, the identification of the output audio signal is provided for use in responding to the input speech signal.
Each frame is classified by a detector (46) as to whether the frame represents voiced, unvoiced or a silence condition.
The method and apparatus makes it possible to make the difference between the original speech signal (120) and the pre-processed speech signal (280) inaudible or nearly inaudible.
