A prototype Searchable Voice Organizer (SVO) has been developed that supports freeform storage and information recall of voice audio. The SVO operates similarly to commercially-available mobile devices called digital voice recorders (DVORs), allowing a user to record many voice notes, as well as navigate these notes with a simple auditory menu interface. However unlike most DVORs, the SVO supports unstructured search of voice audio. Advanced search functionality is supported by phonetic search algorithms developed by Nexidia, Inc. The SVO is designed to be equally useful for persons with visual impairment as well as normally sighted individuals. The approaches utilized by the SVO for searching and navigating speech-based audio may also be useful for multi-purpose mobile devices and applications which make use of similar audio content.
