Abstract
A dictionary creation component [316] converts the normal orthographic written representation of a word into a sequence of symbols that relate to the pronunciation of the word. The symbols may be used to train conventional models for speech recognition. The symbols are not phonemes and do not need to be defined by a speech expert. The symbols are created automatically by the dictionary creation component based on the written representation of the word.
Claims30
A method for specifying a pronunciation of a word comprising:
- receiving a written version of the word defined by a series of characters;
- separating the written version of the word into the series of characters;
- and
- generating symbols that define a pronunciation of the word based solely on the series of characters.
A speech recognition system comprising:
- speech recognition models configured to convert audio containing speech into a transcription of the speech;
- a system dictionary used to train the speech recognition models by providing symbols that define pronunciations of words to the speech recognition models;
- and
- a dictionary creation component configured to generate the symbols for the system dictionary, the symbols being based on written characters of the words.
A method comprising:
- configuring a dictionary creation component to generate symbols that represent pronunciations of words in a target language, the symbols being generated based solely on written representations of the words and the configuring being performed based on the target language;
- providing the dictionary creation component with written words;
- and
- receiving the symbols that represent pronunciations of the written words from the dictionary creation component.
A device comprising:
- means for receiving a written version of a word defined by a series of characters;
- means for separating the written version of the word into the series of characters;
- and
- means for generating symbols that define a pronunciation of the word based on the series of characters.
A computer-readable medium containing programming instructions for execution by a processor, the computer-readable medium comprising:
- instructions for receiving a written version of a word defined by a series of characters;
- instructions for separating the written version of the word into the series of characters;
- and
- instructions for generating symbols that define a pronunciation of the word based solely on the series of characters.
