摘要： Provided is an audio data generation device that achieves high-quality audio generation processing (for example, speech synthesis processing) at high speed without using a GPU that is capable of high-speed processing. The audio data generation device has a configuration in which a multi-stream generation unit obtains a plurality of stream data; furthermore, introducing a learnable convolution processing unit enables adversarial learning with the high-accurate data discrimination device. The audio data generation device obtained through the adversarial learning can perform high-speed and highly accurate audio data generation processing. Furthermore, the audio data generation device has a simple configuration, thus achieving high-quality audio data generation processing (for example, speech synthesis processing) at high speed without using a GPU that is capable of high-speed processing.

摘要： In performing wireless communication between terminals to perform time difference measurement and propagation time measurement, first and second terminals that transmit a signal at least once in attempting space-time synchronization are included. The first terminal measures a reception phase of a locally transmitted signal, and a reception phase of a signal transmitted by the second terminal, adds a positive or negative phase to the measured reception phase, and makes a report to the second terminal. The second terminal measures a reception phase of a locally transmitted signal, and a reception phase of a signal transmitted by the first terminal, and makes a report to the first terminal. The first and second terminals obtain a time difference or propagation time according to a reception phase measured by a local device and reported from a counterpart, and obtain additional information based on a phase reflected in the time difference or propagation time.
