• name: ToBI (Break Index) Annotation

• coding purpose: mark the boundaries between intonation phrases and rate their depth, according to the ToBI scheme

• coding level: Prosody

• data sources: spoken corpora (speech files, orthographic transcription, f0 files)

• module references: orthographic transcription coding module, f0 coding module

• description: A single element <breakindex> is here defined to represent word boundaries and rate them with the proper degree of disjuncture.

• example: The following example shows the 'break index' annotation of the same utterance of section 6.5 ("Show me the cheapest fare from Philadelphia to Dallas excluding restriction VU slash one") using the <breakindex> element:

breakindex.xml

<breakindex id="brkndx_001" type="1" href=word.xml# id(wrd_001) start="2105" end="2105"/>
<breakindex id="brkndx_002" type="1" href=word.xml# id(wrd_002) start="2245" end="2245"/>
<breakindex id="brkndx_003" type="1" href=word.xml# id(wrd_003) start="2355" end="2355"/>
<breakindex id="brkndx_004" type="1" href=word.xml# id(wrd_004) start="2935" end="2935"/>
<breakindex id="brkndx_005" type="4" href=word.xml# id(wrd_005) start="3315" end="3315"/>
<breakindex id="brkndx_006" type="1" href=word.xml# id(wrd_006) start="3565" end="3565"/>
<breakindex id="brkndx_007" type="1p" href=word.xml# id(wrd_007) start="3836" end="3836"/>
<breakindex id="brkndx_008" type="1" href=word.xml# id(wrd_008) start="4325" end="4325"/>
<breakindex id="brkndx_009" type="3" href=word.xml# id(wrd_009) start="5015" end="5015"/>
<breakindex id="brkndx_010" type="1" href=word.xml# id(wrd_010) start="5225" end="5225"/>
<breakindex id="brkndx_011" type="4" href=word.xml# id(wrd_011) start="5855" end="5855"/>
<breakindex id="brkndx_012" type="4" href=word.xml# id(wrd_012) start="7399" end="7399"/>
<breakindex id="brkndx_013" type="4" href=word.xml# id(wrd_013) start="8585" end="8585"/>
<breakindex id="brkndx_014" type="1" href=word.xml# id(wrd_014) start="8825" end="8825"/>
<breakindex id="brkndx_015" type="3" href=word.xml# id(wrd_015) start="9115" end="9115"/>
<breakindex id="brkndx_016" type="1" href=word.xml# id(wrd_016) start="9595" end="9595"/>
<breakindex id="brkndx_017" type="4" href=word.xml# id(wrd_017) start="9880" end="9880"/>
 

• markup declaration:

ELEMENT <breakindex>
ATTRIBUTES
id [ASCII]
type 0, 1-, 1, 1p, 1p?, 2-, 2, 2p, 2p?, 3-, 3, 3p, 3p?, 4-, 4, X
href <word>
start [FLOAT]
end [FLOAT]
 

The attribute `type' can only contain an allowable combination of ToBI symbols, as described in the
ToBI guidelines.
 

• coding procedure: A procedure for break index annotation may be:
• open the following synchronized windows: speech file, f0 curve (<f0> or <closecopy> or <momel>...), <word>
• select a word to define a corresponding <breakindex> element
• listen to a surrounding portion of the speech signal and look at the f0 curve, in order to classify the boundary depth and choose the proper label
