Context-based detection of end-point of utterance

An apparatus for processing an audio signal, the apparatus comprising:

• at least one processor;
• a memory coupled to the at least one processor, the memory including instructions operable to be executed by the at least one processor to perform a set of actions, configuring the at least one processor:
• to receive an audio signal representing an utterance;
• to select a first semantic network based on context of the audio signal, wherein the first semantic network comprises a plurality of slots;
• to perform automatic speech recognition processing on a first portion of the audio signal to generate a first ASR output;
• to determine the first ASR output corresponds to an incomplete sentence based on the first semantic network;
• and
• in response to determination that the first ASR output corresponds to the incomplete sentence, to increase a first timeout threshold associated with the first semantic network.

An apparatus for processing an audio signal, the apparatus comprising:

• means for receiving an audio signal representing an utterance;
• means for selecting a first semantic network based on context of the audio signal, wherein the first semantic network comprises a plurality of slots;
• means for performing automatic speech recognition processing on a first portion of the audio signal to generate a first ASR output;
• means for determining the first ASR output corresponds to an incomplete sentence based on the first semantic network;
• and
• in response to determination that the first ASR output corresponds to the incomplete sentence, means for increasing a first timeout threshold associated with the first semantic network.

A non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause the processor to perform operations comprising:

• receiving an audio signal representing an utterance;
• selecting a first semantic network based on context of the audio signal, wherein the first semantic network comprises a plurality of slots;
• performing automatic speech recognition processing on a first portion of the audio signal to generate a first ASR output;
• determining the first ASR output corresponds to an incomplete sentence based on the first semantic network;
• and
• in response to determination that the first ASR output corresponds to the incomplete sentence, increasing a first timeout threshold associated with the first semantic network.
