COMBINED STATISTICAL AND RULE-BASED PART-OF-SPEECH TAGGING FOR TEXT-TO-SPEECH SYNTHESIS
First Claim
Patent Images
1. A computer-implemented method for text-to-speech (TTS) synthesis, the method comprising:
- in response to a word of a text sequence, generating a first part-of-speech (POS) tag using a statistical POS tagger based on a corpus of trained text sequences, each representing a likely POS of a word for a given text sequence;
generating a second POS tag using a rule-based POS tagger based on a set of one or more rules associated with a type of an application associated with the text sequence; and
assigning a final POS tag to the word of the text sequence for TTS synthesis based on the first POS tag and the second POS tag.

Abstract
In response to a word of a text sequence, a first part-of-speech (POS) tag is generated using a statistical part-of-speech (POS) tagger based on a corpus of trained text sequences, each representing a likely POS of a word for a given text sequence. A second POS tag is generated using a rule-based POS tagger based on a set of one or more rules associated with a type of an application associated with the text sequence. A final POS tag is assigned to the word of the text sequence for TTS synthesis based on the first POS tag and the second POS tag.

9. A machine-readable storage medium having instructions stored therein, which when executed by a machine, cause the machine to perform a method for text-to-speech (TTS) synthesis, the method comprising:
-
in response to a word of a text sequence, generating a first part-of-speech (POS) tag using a statistical POS tagger based on a corpus of trained text sequences, each representing a likely POS of a word for a given text sequence; generating a second POS tag using a rule-based POS tagger based on a set of one or more rules associated with a type of an application associated with the text sequence; and assigning a final POS tag to the word of the text sequence for TTS synthesis based on the first POS tag and the second POS tag. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An apparatus for text-to-speech (TTS) synthesis, comprising:
-
a statistical POS tagger, in response to a word of a text sequence, to generate a first part-of-speech (POS) tag based on a corpus of trained text sequences, each representing a likely POS of a word for a given text sequence; a rule-based POS tagger to generate a second POS tag based on a set of one or more rules associated with a type of an application associated with the text sequence; and a text analyzer coupled to the statistical POS tagger and the rule-based POS tagger to assign a final POS tag to the word of the text sequence for TTS synthesis based on the first POS tag and the second POS tag. - View Dependent Claims (18, 19, 20)
