• name: IPO Annotation

• coding purpose: symbolic annotation of stylized f0 contours as a sequence of pitch movements, according to the the IPO scheme

• coding level: Prosody

• data sources: spoken corpora (speech files, f0 stylised contour files, phonetic transcription)

• module references: f0 coding module (optional), phonetic transcription module

• description: Here we consider two hierarchically ordered elements:
• <closecopy>, representing the inflection points in the stylized curve
• <pitmove>, representing the classified movements from one inflection point to the next one.


In principle, <closecopy> could be directly imported from f0 stylised files or linked to one <f0> element, and <pitmove> should be linked to two consecutive <closecopy> elements.

• example: The following example shows the coding of the Italian sentence "quell'artificio contabile sara` scoperto facilmente" read by a female speaker.

<closecopy id="clscpy_001" value="207" start="130" end="130"/>

pitmove.xml

<pitmove id="pitm_001" type="4" href="closecopy.xml# id(clscpy_001).. id(clscpy_002)"/>

• markup declaration:

ELEMENT <closecopy>
ATTRIBUTES
id [ASCII]
value [FLOAT]
href <f0> ***< (optional) >***
start [FLOAT]
end [FLOAT]

ELEMENT <pitmove>
ATTRIBUTES
id [ASCII]
type 0, Ø, 1, 2, 3, 4, 5, A, B, C, D, E, &2, &3, &4, &A, &C, &D
href <closecopy>..<closecopy>
start [FLOAT]
end [FLOAT]
 

• coding procedure: The most IPO-conformant coding procedure will directly import the stylized f0 curve, obtained with the help of a proper external environment for perceptual, using the <closecopy> element with no need of the <f0> element, and will consist in the following steps:
• open the speech file in order to listen to its intonation
• open the corresponding phonetic segmentation (<phone> and <syllable>)
• import the close copy and display it as a curve, aligned with phonetic segmentation
• define <pitmove> elements by selecting the segments of the stylized curve (delimited by two consecutive <closecopy> elements) and labeling each of them according to the following criteria:
• if it can be considered to coincide with the ideal baseline or topline, by a global look at the curve, label it 0 or Ø respectively
• otherwise choose the proper label on the basis of movement direction and size and of its position in the syllable, judged by looking at its phonetic alignment


If the close copy is not available, the third step may be replaced by the following steps (a very simplified approximation of the correct stylization procedure):

• import or generate automatically the raw f0 curve and display it
• obtain a closecopy by selecting the 'relevant' <f0> points on the raw curve; base such stylization on the shape of the curve, the perceived intonation of the sound file and the alignment with syllables (accents, boundaries...)
