  7. 7. Solving Challenges with Voice Search • Sound Capture J2ME Platforms require JSR-135 with sound record. Requires AMR or other low-bitrate codec. • Environment Mobile environments are typically noisy: utterances come from cars, bars, airports... rarely from quiet home or office environments. • Complex Grammars Must be efficient at handling unstructured/natural utterances – Past: Walled-Garden ODP grammars includes song artists and titles, wallpaper titles, game titles and studios, etc. – Present and Future: Web-Enabled ODPs support millions of music tracks, mobile site names, URLs, free-text queries – requires flexible voice inputs – Consider “grammar-less” voice to text translation using phonemes.
