Audio dialogue system and voice browsing method
First Claim
1. Audio dialogue system, comprising an audio input unit (12) for inputting an audio input signal, speech recognition means (20) associated with said audio input unit (12) for converting said audio input signal into a text input data (21), an audio output unit (12) for outputting an audio output signal, and speech synthesis means (26) associated with an output unit (12) for converting text output data (24) into said audio output signal, browsing means (22) for processing content data (D1), said content data (D1) comprising text content and at least one reference (Ln1, Ln2), said reference comprising a reference aim and activation information, said activation information comprising one or more activation phrases (28), said browsing means (22) being configured to control said speech synthesis means (26) to output said text content, said browsing means being further configured to compare said input text data (21) to said activation phrase (28), and in case of a match, for accessing content data (D2) corresponding to said reference aim, where in case that said text input data (21) is not identical to said activation phrase (28), said browsing means (22) find a match, if said input text data (21) has a meaning similar to said activation phrase (28).

Abstract
An audio dialog system and a voice browsing method are described. An audio input unit (12) acquires an audio input signal. Speech recognition means (20) convert the audio input signal into text input data (21). Content data (D1) comprises text content and at least one reference (LN1). The reference comprises a reference aim and an activation phrase. Browsing means (22) process the content data (D1), controlling speech synthesis means (26) to output the text content. The browsing means (22) compare acquired input text data (21) to the activation phrase (28). If the input text data (21) is not identical to activation phrase (28), a match is still indicated if the input text data and the activation phrase have a similar meaning. In case of a match, content data corresponding to the reference aim is accessed.
