The trial is planned for later this year with up to 10,000 participants and will support translation between Japanese and Chinese, English, Korean, French, German, Indonesian, Italian, Portuguese, Spanish and Thai. For a subset of these languages users will be able to converse face to face because input and output speech will be on the same phone.
The initial trial with 1000 users supported only translations between Japanese and English, Chinese and Korean. NTT said that 70 percent of users indicated that they would like to user the service again.
NTT said it had enhanced its experimental service with two major upgrades in response to feedback from the first trial. First, the user interface now has a repeat button, which enables the speaker to replay the last interpretation if the other party is unable to hear it. Second, a new start-up procedure enables users to launch the service faster.
