A method, system and communication device for enabling uniterm discovery from audio content and voice-to-voice searching of audio content stored on a device using discovered uniterms. Received audio/voice input signal is sent to a uniterm discovery and search (UDS) engine within the device. The audio data may be associated with other content that is also stored within the device. The UDS engine retrieves a number of uniterms from the audio data and associates the uniterms with the stored content. When a voice search is initiated at the device, the UDS engine generates a statistical latent lattice model from the voice query and scores the uniterms from the audio database against the latent lattice model. Following a further refinement, the best group of uniterms is then determined and segments of the stored audio data and/or other content corresponding to the best group of uniterms are outputted.
