Speech-to-speech translation (S2ST) is the process by which a spoken utterance in one language is used to produce a spoken output in another language. The conventional approach to S2ST has focused on processing linguistic information only by directly translating the spoken utterance from the source language to the target language without taking into account paralinguistic and non-linguistic information...
In current DNN/HMM hybrid systems, the DNN models are trained by the 1-of-V targets which are obtained by the Viterbi-based forced-alignment. The states are viewed as unrelated and isolated. In fact, some phonemes are acoustically similar. Especially for Chinese, as a tonal language, its number of similar pairs is quadrupled. To add the similarity information between states into the model training,...
The detection of Out-of-vocabulary (OOV) words is a crucial problem for spoken term detection (STD). In this paper, the use of integration with local acoustic information is investigated to retrieve more OOV words. Tokens with high local acoustic probabilities propagated in the search space at the decoding stage will be forced to propagate to the next frame. In this way, acoustic similar words can...
Virtual Auditory Display (VAD) is a system, which displays acoustic spatial information toward two ears. There are several variations of construction of VAD system. The most popular system is binaural system with headphones. Listener often moves his/her heads unconsciously in listening. Therefore, the rendering acoustic space should be responsive to head movement. Moreover, VAD system responsive to...
Musical instruments radiate sound with specific directivity patterns in 3-dimensional space. The room transfer functions between a source and a receiver in concert halls also depend on the direction of sound radiation and arrival. Listeners perceive sound in 3-dimensional space. This paper explains the methods on the auralization of musical instruments in virtual concert halls that are measured or...
In this work, ultrasonic sensors are adopted to implement a real-time obstacle avoidance system for wheeled robots, so that the robot can continually detect surroundings, avoid obstacles, and move toward the target area. Secondly, six ultrasound sensors installed on the wheeled robot were utilized to detect large obstacles and to obtain distance information between the robot and the obstacle. The...
