The "hot potato voice" is widely recognized as a symptom of peritonsillar cellulitis or abscess; yet there have been no studies assessing the resonance characteristics of the vocal tract in peritonsillitis. Analysis was undertaken of formant frequencies in the articulation of the vowels /i:/. /a:/ and /u:/ in six subjects with peritonsillitis and compared with articulation once the peritonsillitis had settled. Significant variation was found in F1 when articulating /i:/ and in F2 when articulating /a:/, which are explainable by dyskinesis of the peritonsillar musculature. These findings were compared with six subjects articulating the same vowels with and without a hot potato in their mouth. Variation was found in both F1 and F2 when articulating /i:/, which can be related to interference of the potato with movement of the anterior tongue. The changes in the vocal tract differ in these two cases and the title "hot potato voice" in peritonsillitis is a misnomer.
“热土豆嗓音”被广泛认为是扁桃体周围蜂窝织炎或脓肿的一种症状；然而，尚无研究评估扁桃体炎时声道的共振特征。对6例扁桃体炎患者发元音/i:/、/a:/和/u:/时的共振峰频率进行了分析，并与扁桃体炎痊愈后的发音情况进行了比较。发/i:/时F1以及发/a:/时F2出现了显著变化，这可以用扁桃体周围肌肉运动障碍来解释。将这些结果与6名分别在口腔中有和没有热土豆的情况下发相同元音的受试者进行了比较。发/i:/时F1和F2均出现了变化，这可能与土豆对舌前部运动的干扰有关。这两种情况下声道的变化不同，扁桃体炎中的“热土豆嗓音”这一说法是用词不当。
