Abstract (in Japanese) (See Japanese page) 
(in English) We have coded TANDEM-STRAIGHT in the C programming language, have implemented
it onto various devices including smartphones, tablets, PCs, GPGPUs, and so
on, and evaluated the performance. It was found that up-to-date high-performance smart
phones have ability to perform TANDEM-STRAIGHT without simplification faster
than real time. It was also found that the multithread implementation is
quite effective for devices with a multi-core CPU which is included in many up-to-date devices.
In the implementation by using GPGPU, the acceleration gain is remarkable in
the cases where fast GPUs for desktop PCs are used, and especially
more detectors are required in fundamental frequency extraction than those in
TANDEM-STRAIGHT of the MATLAB version.
