Abstract
A playback device includes a first generator, a second generator and a combiner. The first generator processes main audio data to output first audio data. The second generator processes additional audio data to output second audio data. The combiner combines the first audio data with the second audio data. While a sampling frequency of the main audio data is different from a sampling frequency of the additional audio data, the second generator generates the second audio data to adjust a playback speed of the additional audio data based on the sampling frequency of the main audio data.
Claims19
A playback device comprising:
- a first decoder that processes main audio data to output first audio data;
- a microcomputer that processes additional audio data to output second audio data, the microcomputer including a text-to-speech (TTS) engine that generates the additional audio data according to a user operation relative to the playback device in accordance with a settable sampling frequency and a settable playback speed that are settable to the TTS engine, respectively;
- and
- a data processor that combines the first audio data with the second audio data,
- while a sampling frequency of the main audio data is different from a sampling frequency of the additional audio data, the microcomputer generating the second audio data to adjust a playback speed of the additional audio data based on the sampling frequency of the main audio data to synchronize the playback speed of the additional audio data with a playback speed of the main audio data,
- the microcomputer further determining whether the sampling frequency of the additional audio data is adjustable to the sampling frequency of the main audio data by designating the settable sampling frequency that is settable to the TTS engine,
- in response to determining that the sampling frequency of the additional audio data is unadjustable to the sampling frequency of the main audio data by designating the settable sampling frequency that is settable to the TTS engine, the microcomputer adjusting the playback speed of the additional audio data based on the sampling frequency of the main audio data to synchronize the playback speed of the additional audio data with the playback speed of the main audio data by designating the settable playback speed that is settable to the TTS engine independently of designating of the settable sampling frequency that is settable to the TTS engine,
- the microcomputer further generating the additional audio data, and adjusting the playback speed of the additional audio data that has been generated by the microcomputer.
