Speech Signal Processing Technology for Smart Devices to Achieve Multilingual Speech Translation Service
Hitachi, Ltd. today announced that it has developed a speech signal processing technology for smart devices to achieve a better multilingual speech translation service on the market. By removing background noise excluding speaker's voice, this innovative technology offers a speech recognition capability in noisy urban street environments in which its noise level is 70 dB. In addition, its automatic detection of speech intervals enhances usability with an accurate recognition of speech timing without requiring user to press a button for determining the intervals. This technology will contribute to the commercialization of the multilingual speech translation service at service counters in various stores or at information center in public transportation systems.
Hitachi will promote the development of this technology for practical applications, and contribute to provide high satisfactory hospitality services to Japan where many foreigners will visit.
