  • Patent number: 6260016
    Abstract: Prosody templates, constructed during system design, store intonation (F0) and duration information based on syllabic stress patterns for the target word. The prosody templates are constructed so that words exhibiting the same stress pattern will be assigned the same prosody template. The prosody template information is preferably stored in a normalized form to reduce noise level in the statistical measures. The synthesizer uses a word dictionary that specifies the stress patterns associated with each stored word. These stress patterns are used to access the prosody template database. F0 and duration information is then extracted from the selected template, de-normalized and applied to the phonemic information to produce a natural human-sounding prosody in the synthesized output.

  • Patent number: 6185533
    Abstract: A method of separating high-level prosodic behavior from purely articulatory constraints so that timing information can be extracted from human speech is presented. The extracted timing information is used to construct duration templates that are employed for speech synthesis. The duration templates are constructed so that words exhibiting the same stress pattern will be assigned the same duration template. Initially, the words of input text segmented into phonemes and syllables, and the associated stress pattern is assigned. The stress assigned words are then assigned grouping features by a text grouping module. A phoneme cluster module groups the phonemes into phoneme pairs and single phonemes. A static duration associated with each phoneme pair and single phoneme is retrieved from a global static table. A normalization module generates a normalized syllable duration value based upon the retrieved static durations associated with the phonemes that comprise the syllable.

  • Patent number: 5966691
    Abstract: The operating system or application program generates events captured by an event handler mechanism that, in turn, invokes message assembler and graphics assembler modules. The message assembler constructs pseudo-random sentences or notification messages based on the type of event captured and optionally upon selected state variables. The message assembler supplies text strings to a text-to-speech engine. A linguistic database containing a lexicon of predefined words supplies text data that the message assembler concatenates to form the text strings. Text strings are assembled and optionally tagged to alter the message, speaking voice and inflection based on the nature of the message and its context. Graphics elements are assembled by a graphics assembler in response to the event handler and based on optionally supplied user-defined graphics parameters.

  • Patent number: 5924068
    Abstract: An electronic news receiving device receives text data for an electronic edition of a newspaper in the evening and audibly reads the newspaper to the user the next day. The newsreader includes a receiver which receives an electronic edition of a newspaper transmitted by a transmitter at an electronic news preparer's facility. The news preparer may mark words that do not conform to conventional letter-to-sound rules with a pronunciation flag and provide pronunciation data for the words with the electronic edition of the newspaper. The data may be compressed by providing a dictionary in the news receiving device and, at the preparer's facility, translating each word into a dictionary address. The transmission channel may include a telephone line, the vertical blanking interval of a television signal, a cable television channel, an AM/FM subcarrier signal or a satellite channel.

  • Patent number: 5878393
    Abstract: Computer-stored text, such as numerical information, is processed by a word list generator to develop a word list corresponding to those words that are to be spoken by the system. The word list generator assigns a prosodic environment state or token to each entry in the list. The prosodic environment identifies how the word functions in its current prosodic context. Different intonations are applied based on the prosodic environment. Next, the preceding and adjacent words are examined to determine how each word may need to be pronounced differently, based on the ending phoneme of the preceding word and the beginning phoneme of the following word. Using this phonological information along with the prosodic information, a sample list is generated by accessing a dictionary of stored samples. The sample list is then serially played through suitable digital-to-analog conversion circuitry to generate the text-to-speech output.
