Abstract: A timbre-selectable human voice playback system and a timbre-selectable human voice playback method thereof are provided. The timbre-selectable human voice playback system includes a speaker, a storage and a processing apparatus. The storage saves a text database. The processing apparatus is connected to the speaker and the storage. The processing apparatus obtains real human voice signals, converts the text of the text database into original synthetic human voice signals with the text-to-speech technology, and transforms the original synthetic voice signals into timbre-specific human voice signals with a timbre transformation model. The timbre-transformation model is trained with the real human voice signals collected from a specific person. Then, the processing apparatus plays the transformed human voice signals with the speaker. Accordingly, a user can listen to his favorite voice timbre and the transformed voice signal carrying selected content anytime and anywhere.

Abstract: An autonomous robot mainly contains an image capturing device, an interpretation device, a synthesis device, and an audio output device. The image capturing device captures pages of graphical images in which appropriate musical information is embedded, and the interpretation device deciphers and recognizes the musical information contained in the captured graphical image. The synthesis device simulates the sound effects of a type of instrument or a human singer by synthesis techniques in accordance with the recognized musical information. The audio output device turns the output of the synthesis device into human audible sounds. The graphical image of appropriate musical information is prepared in a visually recognizable form. The graphical image can also contain special symbols to give instructions to the autonomous robot such as specifying an instrument.
