Embodiments provide for dialog based speech recognition by clustering a plurality of nodes comprising a dialog tree into at least a first cluster and a second cluster; creating a first dataset of natural language sentences for the first cluster and a second dataset of natural language sentences for the second cluster; generating a first specialized language model (LM) associated with the first cluster based on the first dataset; and generating a second specialized LM associated with the second cluster based on the second dataset, wherein the first specialized LM is different from the second specialized LM.

Dialog based speech recognition

A method for context-dependent emergency reporting includes receiving at a processor of a cellular phone a signal indicative of detecting a contextual cue. The exemplary method also includes receiving at the processor of the cellular phone a signal indicative of detecting a confirmatory cue. The exemplary method further includes the processor of the cellular phone identifying an emergency in response to detecting both the confirmatory cue and the contextual cue; and, in response to identifying the emergency, the processor of the cellular phone alerting a pre-registered recipient of the emergency via a wireless communication module of the cellular phone.
