Next: Synthesis Up: Speechalator: two-way speech-to-speech translation Previous: Recognition


As part of this work we investigated two different techniques for translation, both interlingua based. The first was purely knowledge-based, following our previous work [3]. The engine developed for this was too large to run on the device, although we were able to run the generation part off-line seamlessly connected by a wireless link from the handheld device. The second technique we investigated used a statistical training method to build a model to translate structured interlingua IF to text in the target language. Because this approach was developed with the handheld in mind, it is efficient enough to run directly on the device, and is used in this demo.
