Abstract: A voice rule-synthesizer synthesizes a voice waveform based on the voice data stored in a database, which stores a large number of compressed voice data sections in a data stream. Each voice data section is stored as a plurality of frames compressed in a fixed-length frame format. The storage capacity of the database is reduced because the compressed voice data sections are stored as the data stream.

Abstract: A method for synthesizing a voice waveform includes compressing voice-element data in a fixed length scheme that uses data from a preceding or succeeding frame. The compressed voice-element data of each voice section is expanded, and the preceding or succeeding frame of the expanded voice-element data is discarded. The remaining voice-element data is synthesized after discarding portions of the expanded voice-element data.

Abstract: A method and a system of producing a synthesized voice is provided. A voice sound waveform is provided at a voice sampling frequency based on pronunciation informations. A voice-less sound waveform is produced at a voice-less sampling frequency based on the pronunciation informations. The voice sampling frequency is converted into an output sampling frequency to produce a frequency-converted voice sound waveform with the output sampling frequency, wherein each of the voice sampling frequency and the voice-less sampling frequency is independent from the output sampling frequency. The voice-less sampling frequency is converted into the output sampling frequency to produce a frequency-converted voice-less sound waveform with the output sampling frequency.

Abstract: A voice synthesizing system can make necessary calculation amount satisfactorily small and can make necessary file size small. The system includes a compressed pitch segment database storing compressed voice waveform segments, a pitch developing portion reading out the voice waveform segment from the database and decompressing the compressed data for reproducing an original voice waveform segment when the voice waveform segment necessary for voice waveform synthesis is demanded, and a cache processing portion temporarily storing the voice waveform segment already used in voice waveform synthesis, and when voice waveform segment necessary for voice waveform synthesis is demanded, returning demanded voice waveform segment to a demander when demanded voice waveform segment is already stored, and obtaining the voice waveform segment from the database via the pitch developing portion to hold the obtained voice waveform segment and return to the demander when demanded voice waveform segment is not stored.

Abstract: The invention provides a speech synthesis apparatus which can produce synthetic speech of a high quality with reduced distortion. To this end, upon production of synthetic speech based on prosodic information and phonological unit information, the prosodic information is modified using the phonological unit information, and duration length information and pitch pattern information of phonological units of the prosodic information and the phonological unit information are modified with each other.

Abstract: Outputs of a pulse sensor, a brain wave sensor, a conductivity sensor and an acceleration sensor are input to respectively corresponding condition detecting means, and the condition of the wearer (biological information, motion) is detected by the condition detecting means. The condition determining means determines the operation mode of the hearing aid from the condition of the wearer according to predetermined algorithm. Operation mode control portion drives an earphone based on the operation mode. By this, the characteristics of the hearing aid can be varied adapting to the wearer's condition.

Abstract: A digital hearing aid having a variable hearing compensating characteristics, comprises a hearing compensating circuit having a transposed transversal filter, an analyzer for frequency-analyzing an input signal, a memory storing a hearing characteristics of a person to be fitted with the hearing aid, and a controller receiving a frequency analysis result of the input signal and the hearing characteristics, for deriving coefficients for the transposed transversal filter to supply the derived coefficients to the transposed transversal filter. Since the transposed transversal filter is used, the S/N ration is improved, and the control of the characteristics of the filter becomes easy.

Abstract: A speech synthesizing apparatus for varying a speech characteristic condition is adapted to accept a speech request that does not have a speech characteristic condition and to synthesize a speech responsive thereto. A controlling portion accepts a plurality of speech requests; a speech synthesizing portion switches a plurality of speech characteristics for speech synthesis; a speaker outputs a speech corresponding to an output signal of the speech synthesizing portion; and a synthesizer characteristic table stores speech characteristic conditions synthesized by the speech synthesizing portion. The controlling portion can accept a speech request that does not have a speech characteristic condition. Then, the controlling portion selects an available speech characteristic condition from a synthesizer characteristic table and sends the selected speech characteristic condition to the speech synthesizer.
