Abstract (en)

[origin: CA2263743A1] A natural-language speech control method (20) produces a command (34) for controlling the operation of a digital computer (36) from words spoken in a natural-language. An audio signal that represents the spoken words is processed to generate textual digital-computer-data (24). The textual digitalcomputer-data (24) is then processed by a natural-language-syntactic-parser (26) to produce a parsed sentence in a logical form of the command (28). The parsed sentence is then processed by a semantic compiler (32) to generate the command (34) that controls the operation of the digital computer (36). The command (34) is expressed in a natural-language sentence that has an implied second person singular pronoun subject and the verb is active voice present tense. The preferred method uses a principles-and-parameters (P-and-P) Government-and-Binding-based (GB-based) natural-language-syntactic-parser (26) for resolving ambiguous syntactic structures.
