Application ID: 14459973

Base Claim:
1. A computing device comprising: one or more computer processors; one or more computer-readable media having instructions stored thereon that, responsive to execution by the one or more computer processors, perform operations comprising: determining, based on one speech waveform, a wideband speech feature and a narrowband speech feature; determining, based on the wideband speech feature, an estimate of the narrowband speech feature; determining, based on the narrowband speech feature and the estimate of the narrowband speech feature, an estimation error of the estimate of the narrowband speech feature; transmitting the wideband speech feature and the estimation error to a remote entity; receiving, from the remote entity, data associated with a speech-based service based on the wideband speech feature; and outputting, by the computing device, speech recognition results for the one speech waveform based on the received data associated with the speech-based service.

Claim 2:
2. A computing device as described in claim 1 , wherein the operations further comprise determining if sufficient bandwidth is available to transmit the estimation error of the narrowband speech feature and, when the sufficient bandwidth is available, transmitting the estimation error of the narrowband speech feature estimate.
