The aim of this study was to validate the Acoustic Voice Quality Index 03.01 (AVQIv3) and the Acoustic Breathiness Index (ABI) in the Spanish language.
Concatenated voice samples of continuous speech (cs) and sustained vowel (sv) from 136 subjects with dysphonia and 47 vocally healthy subjects were perceptually judged for overall voice quality and breathiness severity. First, to reach a higher level of ecological validity, the proportions of cs and sv were equalized regarding the time length of 3 seconds sv part and voiced cs part, respectively. Second, concurrent validity and diagnostic accuracy were verified.
A moderate reliability of overall voice quality and breathiness severity from 5 experts was used. It was found that 33 syllables as standardization of the cs part, which represents 3 seconds of voiced cs, allows the equalization of both speech tasks. A strong correlation was revealed between AVQIv3 and overall voice quality and ABI and perceived breathiness severity. Additionally, the best diagnostic outcome was identified at a threshold of 2.28 and 3.40 for AVQIv3 and ABI, respectively.
The AVQIv3 and ABI showed in the Spanish language valid and robust results to quantify abnormal voice qualities regarding overall voice quality and breathiness severity.
本研究旨在验证西班牙语版的声学嗓音质量指数03.01（AVQIv3）和声学呼吸音指数（ABI）。
对136名嗓音障碍患者和47名嗓音健康受试者的连续语音（cs）和持续元音（sv）的拼接语音样本进行总体嗓音质量和呼吸音严重程度的主观判断。首先，为了达到更高的生态效度，分别根据3秒的sv部分和有声cs部分的时长，使cs和sv的比例相等。其次，验证同时效度和诊断准确性。
采用了5位专家对总体嗓音质量和呼吸音严重程度的中等可靠性评价。发现33个音节作为cs部分的标准化，代表3秒的有声cs，可使两项语音任务达到均衡。AVQIv3与总体嗓音质量、ABI与感知呼吸音严重程度之间呈现出强相关性。此外，AVQIv3和ABI的最佳诊断结果分别确定为阈值2.28和3.40。
AVQIv3和ABI在西班牙语中显示出有效且可靠的结果，可用于量化总体嗓音质量和呼吸音严重程度方面的异常嗓音质量。
