Techniques for generating customized synthetic voices personalized to a user, based on user-provided feedback, are described. A system may determine embedding data representing a user-provided description of a desired synthetic voice and profile data associated with the user, and generate synthetic voice embedding data using synthetic voice embedding data corresponding a profile associated with a user determined to be similar to the current user. Based on user-provided feedback with respect to a customized synthetic voice, generated using synthetic voice characteristics corresponding to the synthetic voice embedding data and presented to the user, and the synthetic voice embedding data, the system may generate new synthetic voice embedding data, corresponding to a new customized synthetic voice. The system may be configured to assign the customized synthetic voice to the user, such that a subsequent user may not be presented with the same customized synthetic voice.

User-customized synthetic voice

A system for emulating a subject, to allow a user to interact with a computer generated talking head with the subject's face and voice;

There is provided a speech synthesizer comprising a processor configured to receive one or more linguistic units, convert said one or more linguistic units into a sequence of speech vectors for synthesizing speech, and output the sequence of speech vectors. Said conversion comprises modelling higher and lower spectral frequencies of the speech data as separate high and low spectral streams by applying a first set of one or more statistical models to the higher spectral frequencies and a second set of one or more statistical models to the lower spectral frequencies.

Multi-stream spectral representation for statistical parametric speech synthesis

An acoustic model is adapted, relating acoustic units to speech vectors. The acoustic model comprises a set of acoustic model parameters related to a given speech factor. The acoustic model parameters enable the acoustic model to output speech vectors with different values of the speech factor. The method comprises inputting a sample of speech which is corrupted by noise; determining values of the set of acoustic model parameters which enable the acoustic model to output speech with said first value of the speech factor; and employing said determined values of the set of speech factor parameters in said acoustic model. The acoustic model parameters are obtained by obtaining corrupted speech factor parameters using the sample of speech, and mapping the corrupted speech factor parameters to clean acoustic model parameters using noise characterization paramaters characterizing the noise.

Noise compensation in speaker-adaptive systems

A method of animating a computer generation of a head and displaying the text of an electronic book, such that the head has a mouth which moves in accordance with the speech of the text of the electronic book to be output by the head and a word or group of words from the text is displayed while simultaneously being mimed by the mouth, wherein input text is divided into a sequence of acoustic units, which are converted to a sequence of image vectors and into a sequence of text display indicators. The sequence of image vectors is outputted as video such that the mouth of said head moves to mime the speech associated with the input text with a selected expression, and the sequence of text display indicators is output as video which is synchronized with the lip movement of the head.
