Erlangen, Germany/Moscow, Russia—Yandex, a machine learning-driven artificial intelligence product and service technology company, integrated Fraunhofer upHear voice quality enhancement technology in its first smart speaker product, enabling products to be accurately identified from anywhere in the room Voice instructions.
The Fraunhofer upHear voice quality enhancement technology reduces background noise and echo. With this technology, the new Yandex Smart Speaker, Yandex.Station and Alice (embedded Assistant) can accurately recognize voice commands while the speakers are playing music.
Manfred Lutzky, head of communications and audio at Fraunhofer IIS, stated: "Fraunhofer provides software solutions that enable advanced digital signal processing technology to enhance the audio signal picked up by the far-field microphone array (Yandex.IO) to ensure Yandex's keyword detector and Speech recognizer can receive clear speech signal.Our upHear technology can eliminate the noise and echo that affect the recognition of user speech in smart speaker and extract clear speech signal."
The Fraunhofer upHear voice quality enhancement solution supports full-band audio and has a wide range of applications, including natural language understanding in mobile communications and smart home devices. It is a highly integrated and flexible solution that provides full-duplex talk and voice insertion with superior audio quality. These features are achieved through the combination of advanced multi-channel sound source localization and beamforming techniques with echo cancellation and noise reduction algorithms.
Konstantin Kruglov, director of Yandex's experimental products, said: “We tested a variety of speech enhancement solutions on the Yandex.IO far-field microphone array technology and finally found that Fraunhofer upHear technology was the most effective in helping Alice transition from smart phones to smart home applications. Whether you're standing in front of the device, in the corner of a room, or under poor acoustics, Alice can hear your password.
Yandex's AI voice assistant, Alice, recognizes Russian requests and provides answers to weather, news, maps, traffic, and music streaming through Yandex search engines and services. Yandex built Alice through the study of more than 50 million monthly user interactions supplemented by machine learning techniques and the experience of serving Russian users and using Russian for the past 20 years.
With Yandex's unique speech recognition technology, Alice can provide the world's most accurate Russian speech recognition service with an understanding accuracy close to the human level. In addition, Alice's synthesized voice response sounds very natural. Alice is already built into Yandex's iOS and Android apps. It is also the first virtual assistant designed for the needs of Russian users. With the continuous update of Yandex.Station, Alice will bring a more advanced experience for Russian users.
