The input proces ed text data are compres ed by p c an LZSS proces in , as fol ows

a) Pac proces in

2-byte codes of Katakana an other c aracters are con erted to the cor esp n in 1-byte codes

The seq en e of the codes converted f rom 2-byte Katakana or other c aracters is identified by

the Katakana mode identif ier SO(0x0 ) or default mode identif ier SUB(0x1a) resp ctively, at

the b gin in of the seq en e The seq en e of the 1-byte code of Han ak c aracters is

identified by the Han ak mode identifier SI(0x0f ) at the b gin in of the seq en e

b) LZSS proces in

The LZ S algorithm with sl de dictionary of 1 0 4-byte len th is employed Character codes are

proces ed byte by byte an stored in the output buff er fom the MSB of the first byte When the

last byte of the output buf fer has u u ed bits, they wi b f il ed with “0”

Annex A

(inf or mative)

Input processing (Japanese texts)

The au itory presentationeq ipment s nthesizes voice f rom text data en odedin a texture ma

If the text data contain control codes for text, the text-to-sp ec can ot cor ectly b worked

Those control codes for text have to b removed in the input proces in

For the text-to-sp ec some voice pro erties (male/female, etc.) can b sp cified an a

p rtic lar pron n iation of Kanj canb sp cifiedby ad in controlcodesfor sp ec in the input

proces in

A 2 Removal of control codes f or text

For a pro riate text-to-sp ec workin , the control codes for text: 0x01 throu h 0x0 , 0x0 ,

0x0c, 0x0 throu h 0x1f an 0x7f (hexadecimal re resentation of Shift JIS code, JIS X 0 0 )

have to b removed In the au itory presentation eq ipment, ta (0x0 ) is con erted to Toten

(en of senten e in Ja anese) an lne f eed (0x0 ) is con erted to 0x0d0 an to Kuten (p u e

in senten e in Ja anese)

Other sp cial c aracters that can ot cor esp n to an a pro riate text-to-sp ec s ould b

removed f rom input texts

A 3 Specif ication of particular pronunciation of Kanj

When input texts in lu e Kanj c aracters that s ould b con erted to voice with a p rtic lar

pron n iation by the au itory presentation eq ipment, the pron n iation of Kanj (s) can b

sp cified by s c e din a colon an the Han ak Katakana strin re resentin the

pron n iation The seq en e of Kanj (s), a colon an the Han ak Katakana strin s al be

en losed in a p renthesis, as s own b low

(Kanj (s):Han ak Katakana strin re resentin the Kanj (s) pron n iation)

Example

( 金田一君:ｶﾈﾀﾞﾊ ﾞﾒ ﾝ)

When input texts in lu e alpha-n meric c aracters that s ould b con erted to voice with a

p rtic lar pron n iation by the au itory presentation eq ipment, the alpha-n meric c aracters

s al b re laced with cor esp n in Kanj (s) or Zen ak Katakana(s) Then the pron n iation

s al b sp cified by s c e din a colon an the Han ak Katakana strin re resentin the

pron n iation The seq en e of Kanj(s) or Zen ak Katakana(s), a colon an the Han ak

Katakana strin s al b en losed in p rentheses

A 4 Specif ication of voice properties

In the au itory presentation eq ipment, some voice pro erties can b sp cified by ad in

control codes f or sp ec ju t precedin a senten e The control code for sp ec can b

sp cified in e c senten e f or control n its voice pro erties.It isp s ible,for example, that the

f irst senten e is sp ken in a male voice an the secon senten e in a female voice

The control codes for sp ec are s own in Ta le A.1

Table A.1 – Control code f or spe c

Co trol c d c n ists of c ntrol c ara ters a d a s c e din n meric l v lu

To the senten e without control codes at its b gin in , control codes of the precedin senten e

a ply Examples of the control codes for sp ec are s own b low:

^V0^H3^P4 (male voice, pitc level 3, lou nes level 4)

^V1^H4 (female voice, pitc level 4)

^V0^H3 (male voice, pitc level 3)

If no control code is sp cif ied, the def ault values of voice pro erties in Ta le A.1 a ply It is the

case eq ivalent to the sp cification of voice pro erties with control codes ^V0^H3^P4 (male

voice, pitc level 3, lou nes level 4)

Identifyin a p ge b u dary, input texts in a p ge are en oded to a texture ma If a senten e

contain a p ge b u dary, it is de lt with on the next p ge

The au itory presentation eq ipment identifies the en of a senten e by the c aracters or

c aracter strin s s own in Ta le A.2 an se arates e c senten e f rom input texts After the

en of senten e, NUL (0x0 ) is in erted as a delmiter
