听觉神经的多通道电刺激结合言语阅读已经帮助2名完全听力损失的语言后耳聋患者理解日常情况下的跑步言语。这一点通过开放式语音平衡单词测试得到了证实，其中患者在孤立单词中获得了60%和40%的分数，在孤立单词中获得了80%和73%的音素分数。测试还表明，与单独的言语阅读相比，人工耳蜗植入物使1名患者的单词识别能力提高了4倍，另一名患者的单词识别能力提高了2倍。利用语音处理器，提取出浊音的频率和能量以及在中频范围内的主频谱峰的频率和能量。发声的参数确定了所有电极的刺激速率，中频范围内的主频谱峰的参数确定了电极刺激的部位和电流水平。
Multiple-channel electrical stimulation of the hearing nerve in conjunction with speechreading has helped 2 post-lingually deaf patients with total hearing losses understand running speech in every day situations. This was confirmed using open-set phonetically balanced word tests, where the patients achieved 60 and 40% scores with isolated-words and 80 and 73% for phonemes in isolated words. The tests also showed that the cochlear implant improved word recognition by a factor of 4 in 1 patient and 2 in another, compared with speechreading alone. The speech processor used, extracted the voicing frequency and energy and the frequency and energy of the dominant spectral peak in the mid-frequency range. The parameters for voicing determined the rate of stimulation for all electrodes and the parameters for the dominant spectral peak in the mid-frequency range determined the site of electrode stimulation and current level.
