Insertions and deletions Sample Clauses

Insertions and deletions. Regarding phones labels, we have not analyzed the overall rate of substitutions because the annotators had instructions to focus their corrections on the phone boundaries and on the voicing and devoicing of obstruent consonants. With regard vowel timbre, confusions concern essentially mid-close and mid-open vowels, which are not easy to detect. Thus we ask annotators not to take too much time on this phenomenon. We can observe in Table 3 that there is a very low rate of deletions and insertions between the seven annotators and the expert. Recall that the 18 sentences have a total of 625 phones. 40% of insertions or omissions concern the schwa. This result is rather expected because schwa is often a very short and weak vowel whose presence is sometimes difficult to detect. Table 3. Percentage of insertions and deletions for each annotator.
