<p>new article- Text to Speech special inflection codes.</p> <p><b>New page</b></p><div>Special Inflection codes used by the TI [[Text-to-Speech]] disk program.<br /> <br /> In general, the allophone code space is subdivided into two areas. The first one, ranging in numbers from<br /> 1 through 240, is the [[Standard allophone codes for TI Text to Speech—English|actual allophone range]]. Presently, only 126 of those 240 codes are actually used.<br /> <br /> The second range, from 241 through 255, is used for special function codes. Each special function has up<br /> to two additional numbers associated with it. This appendix describes the codes currently used.<br /> <br /> ==Inflection code 249==<br /> Secondary stress-point. Depending on the state the stringer is in, the stress-point will either be given<br /> the current vowel pitch level, and the vowel pitch will be incremented by a computed delta amount,<br /> or, after an upgoing primary stress-point, the stress-point will be raised one level above the current<br /> vowel pitch level, and the vowel pitch will be decremented by the computed delta amount.<br /> ==Inflection code 250==<br /> Sentence break code. Resets parameters to default values given by SPEAK routine. This code is<br /> followed by two parameters: the number of secondary stress-points before and after the primary<br /> stress-point, respectively. If the primary stress-point is a rising (question mark) stress, the second<br /> parameter indicates the number of vowels after the primary stress-point. If the first parameter has<br /> either of the values 254 or 255, the second parameter will indicate the total number of vowels in the<br /> phrase. A value of 254 or 255 for the first parameter indicates that the entire phrase should have a<br /> rising or falling tendency respectively. This tendency is spread out over at least 8 vowels, and slopes<br /> over 15% as indicated by the slope parameter in the SPEAK call.<br /> ==Inflection code 251==<br /> New default slope parameter. The number following this code indicates the new slope parameter to<br /> be used. As usual, the slope indicates 3 times the actual slope value, to allow for fractional values of<br /> the slope. Normally the slope parameter should be selected to be approximately 10% of the pitch<br /> parameter.<br /> ==Inflection code 252==<br /> New default pitch parameter. The number following this parameter indicates the new default pitch<br /> level to be used. Notice that this pitch level is only valid for the current phrase. Permanent pitch level<br /> modifications have to be made using the parameters in the SPEAK routine.<br /> ==Inflection code 253==<br /> Rising pitch contour. Used for question-type phrases at primary stress-point. Will cause the next<br /> allophone to be gradually raised in pitch, starting below the current default level, and ending above<br /> the current default level. If no vowels are following the primary stress-point, as indicated by the most<br /> recent 250 code, the allophone will be put at the standard pitch level, but along a gradually rising<br /> slope, starting at the current level (with the current stressed allophone), and rising to a higher level.<br /> <br /> Taken from the Text to Speech disk manual.</div>
