Problems solved by technology

[0019] However, there is no definition regarding the representation of speech (human voice) in SMF and SMAF
[0020] Therefore, it is conceivable to amplify MIDI events such as SMF to synthesize speech, but in this case, there is a problem of complicated processing when only the speech part is taken out once for speech synthesis.

Embodiment Construction

[0054] figure 1 It is a view showing an embodiment of the data exchange format of the voice reproduction sequence data of the present invention. In this figure, 1 is a file having the data exchange format of the present invention. This file 1 has a byte slice structure as a basic structure similarly to the above-mentioned SMAF file, and has a header portion and a body portion (file byte slice).

[0055] A file ID (byte slice ID) for identifying a file and a byte slice size indicating the length of the subsequent body part are included in the header part.

[0056] The text part is a sequence of byte chunks, and in the example shown in the figure, it includes content information byte chunks (Contets InfoChunk) 2, optional data byte chunks (Optional Data Chunk) 3, and HV (human voice) containing voice reproduction sequence data Path byte slice 4. exist figure 1 Although only one HV path byte slice #00 is described as the HV path byte slice 4, a plurality of HV path byte sli...

Abstract

Provided is a sequence data conversion format with which musical piece sequence data and audio reproduction sequence data can synchronously be reproduced.A file is in chunk format and includes a content information chunk, an optional data chunk, and an HV track chunk for audio reproduction including information for management. Audio reproduction sequence data included in the HV track chunk can select a text description type consisting of text information showing a reading of a speech to be synthesized and a rhythm symbol specifying a speech expression, a phoneme description type consisting of phoneme information representing the speech to be synthesized and rhythm control information, or a formant frame description type consisting of formant control information of each frame time showing the speech to be reproduced. The HV track chunk can be included in an SMAF file as well as a score track chunk etc.

Description

technical field [0001] The present invention relates to a music and voice reproduction device and its control method, storage medium, server device and computer program. Background technique [0002] SMF (Standard MIDI file format: Standard MIDI file format) and SMAF (Synthetic Music Mobile Application Format: Synthetic Music Mobile Application Format) are known as data exchange formats for distributing or mutually utilizing data for expressing music through sound sources. SMAF is a data format standard for displaying multimedia content on mobile terminals and the like (see Non-Patent Document 1). [0003] Refer below Figure 15 Explain SMAF. [0004] In this figure, symbol 100 is a SMAF file, and a data block called a chunk is a basic structure. A byte slice is composed of a header portion of fixed length (8 bytes) and a text portion of arbitrary length, and the header portion is further divided into a 4-byte slice ID and a 4-byte slice size. The byte slice ID is used as...
