Description
Technical field
The present invention relates to text conversion is the system of voice.
Background technology
Text-to-speech converter (text-to-speech converter) be a kind of be the device of voice with text conversion.For people visually impaired, this device can help them to listen to extraneous information.Under particular environment, this device also is a kind of important outfit of common people's acquired information, when for example driving, or makes telephonic the time.And the source of these information, but e-file, or see through the Word message that light scanning unit and character recognition device are converted.
In daily life, the source of electronic type information is numerous day by day, and becomes progression to increase, for example, and Email, schedule, E-News, stock information and the world wide web that gets most of the attention.These electronic information to be converted to digital speech, if adopt artificial recording digitized processing in addition again, not only need to expend huge manpower and huge storage space, and artificial record type can't be applicable to that computer system adjusts the electronic information of generation automatically according to user's demand.
For the designer of text-to-speech converting unit, how various scripts are applicable to that the electronic information of Visual Display is converted to the voice pattern, determine it is a kind of challenge.Wherein most important reason is, presenting of electronic information not only needs to present its word content, simultaneously also need to consider the presentation mode of these word contents, for example the capital and small letter in Visual Display, runic, italic, paragraph type and enumerate presentation mode such as pattern.When carrying out the text-to-speech conversion, form and font control code that these are used to control Visual Display originally can not directly be converted to voice.Punctuation mark in word content can not directly be converted to voice.In addition, at different front and back literary compositions, the pronunciation of a word string also has different manners of articulation, and for example distorsion word of Chinese pronunciation is exactly a typical example.In order to address these problems, previous technological invention has proposed various solutions.
United States Patent (USP) the 5th, 555 has disclosed a kind of text-to-speech switch technology that solves this class problem No. 343.Wherein comprise the format and the processing mode of font control code, and the disposal route of punctuation mark and specific alphanumeric form.The method adopts first form of building up in advance with format and the corresponding Chinese idiom sound of font control code control code, is used for controlling the rate of articulation or volume.The method adopts second form of building up in advance with the colloquial literal word string of the corresponding one-tenth of specific alphanumeric form.These specific alphanumeric forms comprise the digital word string that is used for express time and separates with colon, be used for representing the date and the digital word string separated with oblique line and be used for representing archives catalog and the literal word string separated with oblique line etc.The method adopts the 3rd form of building up in advance with punctuation mark or corresponding colloquial literal word string of one-tenth of mathematical operation symbol or voice control code.The method is used a form of building up in advance, to determine a character of importing for can pronounce or can not pronounce.Run into the character that can not pronounce,, determine suitable articulation type just according to aforesaid first, second and third form of building up in advance.
United States Patent (USP) the 5th, 634, the another kind of text-to-speech switch technology that solves this class problem of No. 084 announcement.The method choosing will input literal according to contextual relation be categorized into numeral, linear module, geographical term in time between classification such as date.Again the literal after this classification is launched according to one or more different classes of abbreviation word table, and the colloquial words of corresponding one-tenth.The for example abbreviation of place name " SF, CA ", the method can be converted into " San Francisco Califomia (San Francisco, California) "; Also " MPEG " can be converted to colloquial " m peg ".
Because popularizing of Internet (Internet) and world wide web (World Wide Web), world wide web has become one of main source of current electronic information.(we are referred to as the hypermedia file to the most of employing of electronic information on world wide web hypermedia indicating language for Hyper Text Markup Language, form HTML).Hypermedia file and the different place of other e-files are in its source document, except file content, also to contain hypermedia label (HTML tag).The hypermedia label is the defined word tag of hypermedia indicating language, is used for the content and structure of markup document, or the demonstration of file control.For example, this example is represented the source document of one section hypermedia file below:
＜！BODY BGCOLOR＝#DBFFFF＞ ＜body bgcolor＝white＞ ＜CENTER＞ ＜map name＝“Main”＞ ＜area shape＝“rect”corrds＝“157，12，257，112”href＝“Main.html”＞ ＜area shape＝“rect”corrds＝“293，141，393，241”href＝“VRML.html”＞ ＜area shape＝“rect”corrds＝“18，141，118，241”href＝“VRML.html’＞ ＜area shape＝“rect”corrds＝“157，226，257，366”href＝“Main.html”＞ ＜/map＞ ＜img src“Images/Main.gif”usemap＝“#Main”border＝0＞＜/img＞ <!-- SIPO <DP n="2"> --> <dp n="d2"/> ＜br＞＜br＞＜br＞＜br＞ ＜b＞ ＜font size＝3 color＝black＞ Welcome to the VR workshop of our company ＜/font＞ ＜a href＝“http：//www.ccl.itri.org.tw”＞＜font size＝3color＝blue＞ITRI＜/font＞＜/a＞ ＜font size＝3 color＝black＞/＜/font＞ ＜a herf＝“http：//www.ccl.itri.org.tw”＞＜font size＝3color＝blue＞CCL＜/font＞＜/a＞ ＜font size＝3 color＝black＞.We have been＜br＞ developing some advanced technologies as follows，＜br＞ ＜/b＞ ＜ul＞ ＜a href＝“Main.html”＞ ＜li＞＜font size＝3 color＝blue＞Pano VR＜/font＞ ＜/a＞ ＜font size＝3＞(A panoramic image-based VR)＜/font＞＜br＞ ＜a href＝“VRML.html”＞ ＜li＞＜font size＝3 color＝blue＞Cyber VR＜/font＞ ＜/a＞ ＜font size＝3＞(A VRML 1.0browser)＜/font＞＜br＞ ＜/ul＞ ＜br＞＜br＞ ＜a href＝“Winner.html”＞＜img src＝“Images/Winner.gif”border＞＜/img＞＜/a＞＜br＞ ＜/a＞ ＜br＞＜br＞ ＜font size＝3 color＝black＞ ＜br＞You are the＜img src＝“cgibin/Count.cgi？df＝vvr.dat”border＝0align＝middle＞thvisitor＜br＞ <!-- SIPO <DP n="3"> --> <dp n="d3"/> ＜/font＞ ＜HR size＝2 WIDTH＝480 ALIGN＝CENTER＞ (C)Copyright 1996 Computer and Communication Laboratory，＜br＞ Industrial Technology Research Institute，Taiwan，R.O.C. ＜/BODY＞
Can be seen by this example, in the source document of hypermedia file, all be displayable character, do not have the special control code that can't show.The hypermedia label is with "＜" and "〉" indicate, and be divided into start-tag and end-tag.Open the beginning label start with "＜", end-tag then with " 〉/" start.Therefore, "＜font size=3 color=black〉" be the start-tag of " font " hypermedia label, "＜/font〉" then be its end-tag.
The hypermedia indicating language will be given special meaning by the word content that start-tag and end-tag indicated of hypermedia label, to express the structure of file, for example title, paragraph, enumerate and form etc.The display mode of these structural details is then controlled by the world wide web browse unit.Therefore, same hypermedia file on different global information visit unit or display system, has different display modes.In addition, the hypermedia label also allows the arrangement mode of nido, for example in last example, "＜b〉" reach "＜font size=3 color=black〉" be added on " Welcome to the VRworkgroup of our company " in the mode of nido.
Though above-mentioned example is the hypermedia file of writing with English, the word content of hypermedia file allows the language with other, as in, day and Korean etc.For the reader of general world wide web Chinese web page, to some English specific terms, reach nouns such as " HTML " as " Web ", " World Wide Web ", not strange.Therefore in general Chinese web page, regular meeting mixes English proper noun.On the other hand, in files such as the technological document of being write with the hypermedia indicating language, notice of meeting and p.m.entry, also often use English proper noun or abbreviation.Therefore in general world wide web webpage, often mixing has multiple language.In addition, we need consider that also same word string has the problem of multiple pronunciation, Zhong Wen distorsion word for example, and same word has different articulation types at different speech or hereinafter preceding.
Above-mentioned traditional text-to-speech converting unit and not to be suitable for the hypermedia file conversion be voice signal.In the process of conversion, at first the problem that must solve is exactly how to analyze the hypermedia file to know the hypermedia label to debate.Because the hypermedia label forms by displayable character, but not special control code, and the hypermedia label allows the arrangement mode of nido formula, therefore the technological invention of relevant text-to-speech converting unit and be not suitable for and analyze the hypermedia file.Moreover above-mentioned traditional text-to-speech converting unit also can't solve the distorsion word problem.Though some Chinese text speech conversion unit can solve the distorsion word problem of part.But these text-to-speech converting units are not considered the problem that multilingual mixes.Emphasis of the present invention is promptly overcoming these problems.
