Synthesis-based pre-selection of suitable units for concatenative speech
View Patent ↗The instructions on the computer-readable medium control a computing device to perform the steps: selecting at least one phoneme from a triphone unit selection database as at least candidate phoneme for use in speech synthesis, selecting a set of phonemes from the at least one candidate phonemes and synthesizing speech using the selected set of phonemes.
1. A system for synthesizing speech, the system comprising:
a processor;
a module configured to control the processor to select at least one phoneme unit from a triphone unit selection database as at least one candidate phoneme to use in synthesizing speech;
a module configured to control the processor to select a set of phonemes from the at least one candidate phoneme, the module selecting the set of phonemes by appyling a Viterbi search in a cost process; and
a module configured to control the processor to synthesize speech using the selected set of phonemes.
2. The system of claim 1 , further comprising: a module configured to control the processor to parse received input text into recognizable units that are used to synthesize speech.
3. The system of claim 2 , wherein the module configured to control the processor to parse the received input text further:
controls the processor to apply a text normalization process to parse the received text into known words and convert abbreviations into known words; and
controls the processor to apply a syntactic process to perform a grammatical analysis of the known words and identify their associated part of speech.
4. A method for synthesizing speech, the method comprising:
selecting at least one phoneme unit from a triphone unit selecting database as a candidate phoneme to use in synthesizing speech;
selecting a set of phonemes from the at least one candidate phoneme, wherein the selecting applies a Viterbi search in a cost process; and
synthesizing speech using the selected set of phonemes.
5. The method of claim 4 , further comprising: parsing the received input text into recognizable units that are used to synthesize speech.
6. The method of claim 5 , wherein the step of parsing the received input text further comprises:
applying a text normalization process to parse the received text into known words and convert abbreviations into known words; and
applying a syntactic process to perform a grammatical analysis of the known words and identify their associated part of speech.
7. A tangible computer-readable medium storing a computer program for controlling a computing device to synthesize speech, the instructions comprising:
selecting at least one phoneme unit from a triphone unit selection database as at least one candidate phoneme to use in synthesizing speech;
selecting a set of phonemes from the at least one candidate phoneme, wherein the selecting applies a Viterbi search in a cost process; and
synthesizing speech using the selected set of phonemes.
8. The computer-readable medium of claim 7 , wherein the instructions further comprises: parsing the received text into recognizable units that are used to synthesize speech.
9. The computer-readable medium of claim 8 , wherein step of parsing the received input text further comprises:
applying a text normalization process to parse the received text into known words and convert abbreviations into known words; and
applying a syntactic process to perform a grammatical analysis of the known words and identify their associated part of speech.
