Abstract: A computer to telephone interface card comprises a plurality of audio data input ports, a mixer, and a converter. The mixer receives audio input data from audio data input ports and, in real-time, generates a mixed audio output data signal at the mixer output. The converter has an output connecting to a phone line to generate and provide mixed audio output to the phone line based on the audio input data received at the plurality of audio data input ports.

Abstract: A method for converting text to concatenated voice by utilizing a digital voice library and a set of playback rules is provided. Multiple voice recordings correspond to a single speech item and represent various inflections of that single speech item. The method includes determining syllable count and impact value for each speech item in a sequence of speech items. A desired inflection for each speech item is determined based on the syllable count and the impact value and further based on a set of playback rules. A sequence of voice recordings is determined by determining a voice recording for each speech item based on the desired inflection and based on the available voice recordings that correspond to the particular speech item. Voice data are generated based on a sequence of voice recordings by concatenating adjacent recordings in the sequence of voice recordings.

Abstract: A method for converting text to concatenated voice by utilizing a digital voice library and a set of playback rules is provided. The digital voice library includes a plurality of speech items and a corresponding plurality of voice recordings. Each speech item corresponds to at least one available voice recording. Multiple voice recordings that correspond to a single speech item represent various inflections of that single speech item. The method includes receiving text data, converting the text data into a sequence of speech items in accordance with the digital voice library. The method further includes establishing multiple voice recordings in the digital voice library that correspond to a single inflection of a single speech item, for a plurality of inflections of a plurality of speech items, that represent various ligatures for the single inflection of the single speech item with adjacent speech items.
