Spoken dialog system using prominence
First Claim
1. A method for analyzing speech in a spoken dialog system, comprising the steps of:
- accepting an utterance by at least one means for accepting acoustical signals, in particular a microphone,analyzing, by a computer processor, the utterance and obtaining prosodic cues from the utterance using at least one processing engine,wherein the utterance is evaluated based on the prosodic cues to determine a prominence of parts of the utterance, and wherein the utterance is analyzed to detect at least one marker feature indicative of the utterance containing at least one part to replace at least one part in a previous utterance, the part to be replaced in the previous utterance being determined based on the prominence determined for the parts of the previous utterance and the replacement parts being determined based on the prominence of the parts in the utterance, and wherein the previous utterance is evaluated with the replacement part(s).

Abstract
The invention presents a method for analyzing speech in a spoken dialog system, comprising the steps of: accepting an utterance by at least one means for accepting acoustical signals, in particular a microphone, analyzing the utterance and obtaining prosodic cues from the utterance using at least one processing engine, wherein the utterance is evaluated based on the prosodic cues to determine a prominence of parts of the utterance, and wherein the utterance is analyzed to detect at least one marker feature, e.g. a negative statement, indicative of the utterance containing at least one part to replace at least one part in a previous utterance, the part to be replaced in the previous utterance being determined based on the prominence determined for the parts of the previous utterance and the replacement parts being determined based on the prominence of the parts in the utterance, and wherein the previous utterance is evaluated with the replacement part(s).

12. A spoken dialog system, comprising
at least one means for accepting acoustical signals, in particular a microphone, for accepting an utterance, at least one processing engine for analyzing, by a computer processor, the utterance and to obtain prosodic cues from the utterance, wherein the processing engine is adapted to evaluate the utterance based on the prosodic cues to determine a prominence of parts of the utterance, and wherein the processing engine is adapted to analyze the utterance to detect at least one marker feature indicative of the utterance containing at least a part to replace at least a part in a previous utterance accepted by said acoustical signal means, the part to be replaced in the previous utterance being determined based on the prominence determined for the parts of the previous utterance and the replacement parts being determined based on the prominence of the parts in the utterance, and wherein the previous utterance is evaluated with the replacement part(s).

13. A spoken dialog system, comprising:
-
at least one means for accepting acoustical signals, in particular a microphone, for accepting an utterance, at least one processing engine for analyzing, by a computer processor, the utterance and to obtain prosodic cues from the utterance, wherein the processing engine is adapted to evaluate the utterance based on the prosodic cues to determine a prominence of parts of the utterance, and wherein the processing engine is adapted to analyze the utterance to detect at least one marker feature indicative of the utterance containing at least a part to replace at least a part in a previous utterance accepted by said acoustical signal means, the part to be replaced in the previous utterance being determined based on the prominence determined for the parts of the previous utterance and the replacement parts being determined based on the prominence of the parts in the utterance, and wherein the previous utterance is evaluated with the replacement part(s); and
wherein the system is configured to perform a process comprising;accepting the utterance by the at least one means for accepting acoustical signals, in particular the microphone, analyzing the utterance and obtaining the prosodic cues from the utterance using the at least one processing engine, wherein the utterance is evaluated based on the prosodic cues to determine the prominence of parts of the utterance, and wherein the utterance is analyzed to detect the at least one marker feature indicative of the utterance containing the at least one part to replace the at least one part in the previous utterance, the part to be replaced in the previous utterance being determined based on the prominence determined for the parts of the previous utterance and the replacement parts being determined based on the prominence of the parts in the utterance, and wherein the previous utterance is evaluated with the replacement part(s).
