3 名听力正常的受试者评估了将语音阅读（即唇读）与从语音低频区域提取的韵律信息相结合的能力。受试者在连接的话语跟踪程序中进行了测试，该程序测量口语文本可以无任何错误地重复的速度。接受条件包括单独语音朗读（SA）、语音朗读加幅度包络提示（AM）、语音朗读加基频提示（FM）以及语音朗读加强度调制基频提示（AM + FM）。在第二个实验中，1 名受试者在语音阅读加发声持续时间提示条件 (DUR) 中接受了进一步测试。语音朗读性能在 AM + FM 条件下最好（83.6 个词/分钟），在 SA 条件下最差（41.1 个词/分钟）。 AM、FM 和 DUR 条件下的跟踪水平分别为 73.7、73.6 和 65.4 个字/分钟。当受试者被允许聆听说话者的正常（未过滤）语音（NS 条件）时获得的平均跟踪速率为 108.3 个词/分钟。显然，语音朗读者可以利用与语音节奏、重音和语调模式相关的信息来提高他们的语音朗读表现。
The ability to combine speechreading (i.e., lipreading) with prosodic information extracted from the low-frequency regions of speech was evaluated with 3 normally hearng subjects. The subjects were tested in a connected discourse tracking procedure which measures that rate at which spoken text can be repeated back without any errors. Receptive conditions included speechreading alone (SA), speechreading plus amplitude envelope cues (AM), speechreading plus fundamental frequency cues (FM), and speechreading plus intensity-modulated fundamental frequency cues (AM + FM). In a 2nd experiment, 1 subject was further tested in a speechreading plus voicing duration cue condition (DUR). Speechreading performance was best in the AM + FM condition (83.6 words/min) and worst in the SA condition (41.1 words/min). Tracking levels in the AM, FM, and DUR conditions were 73.7, 73.6, and 65.4 words/min, respectively. The average tracking rate obtained when subjects were allowed to listen to the talker''s normal (unfiltered) speech (NS condition) was 108.3 words/min. Apparently, speechreaders can use information related to the rhythm, stress, and intonation patterns of speech to improve their speechreading performance.
