摘要： Wideband speech is synthesized from a bandlimited speech signal, for example from speech which has been transmitted via the public switched telephone network. Due to the nature of the vocal tract, there is a correlation between a bandlimited signal and those parts of an original wideband speech signal which are missing from that signal. Narrowband speech is characterized in terms of estimated formant frequencies provided by a peak picker. The frequency of formants in speech give a good indication, for voiced sounds, as to the shape of the vocal tract. The set of frequencies provided by the peak picker is used to access a codebook which provides synthesis parameters for use by a synthesizer.

摘要： Portions of recorded speech waveform (e.g., corresponding to phonemes) are combined to synthesize words. In order to provide a smoother delivery, each voiced portion of a waveform portion has its amplitude adjusted to a predetermined reference level. The scaling factor used is varied gradually over a transition region between such portions and between voiced and unvoiced portions.

摘要： This invention relates to the generation of synthetic speech and specifically to the production of a digital waveform from a text in phonemes. The invention uses a linked database which comprises an extended text in phonemes and its equivalent in the form of a digital waveform. The two portions of the database are linked by a parameter which establishes equivalent points in both the phoneme text and the digital waveform. The input text (in phonemes) is analyzed to locate matching portion in the phoneme portion of the database. This matching utilises exact equivalence of phonemes where this is possible; otherwise relation between phonemes is utilised. The selection process identifies input phonemes in context whereby improved conversions are obtained. Having analyzed the input text into matching strings in the input form of the database beginning and ending parameters for the sections are established. The output text is produced by abutting sections of the digital waveform and defined by the beginning and ending parameters.
