Abstract:
1. In a method for performing real-time continuous speech recognition distributed across a client device and a server device, and which transfers speech data from an utterance to be recognized using a packet stream of extracted acoustic feature data including at least some cepstral coefficients, the improvement comprising: extracting prosodic features at the client device from the utterance to generate extracted prosodic data; transferring said extracted prosodic data with said extracted acoustic feature data to the server device; recognizing words spoken continuously in said utterance at said server device based on said extracted acoustic feature data; and recognizing an emotion state of a speaker of the utterance at said server device based on at least said extracted prosodic data; wherein operations associated with recognition of prosodic features as well as words in the utterance are distributed across the client device and server device, such that a first set of prosodic recognition operations take place at the client device, and a second set of prosodic recognition operations take place at the server device to recognize said emotion state; and wherein said prosodic data and acoustic feature data are transmitted using different priorities.
