    • Techniques are disclosed for modifying speech quality in a conversation over a voice channel. For example, a method for modifying a speech quality associated with a spoken utterance transmittable over a voice channel comprises the following steps. The spoken utterance is obtained prior to an intended recipient of the spoken utterance receiving the spoken utterance. An existing speech quality of the spoken utterance is determined. The existing speech quality of the spoken utterance is compared to at least one desired speech quality associated with at least one previously obtained spoken utterance to determine whether the existing speech quality substantially matches the desired speech quality. At least one characteristic of the spoken utterance is modified to change the existing speech quality of the spoken utterance to the desired speech quality when the existing speech quality does not substantially match the desired speech quality. The spoken utterance is presented with the desired speech quality to the intended recipient.
    • 公开了用于通过语音信道修改会话中的语音质量的技术。 例如,用于修改与通过语音信道传输的口语发音相关联的语音质量的方法包括以下步骤。 口语发音是在接受口语发音的口语发音之前获得的。 确定说话话语的现有语音质量。 将口语发音的现有语音质量与与至少一个先前获得的口语话语相关联的至少一个期望语音质量进行比较,以确定现有语音质量是否与所需语音质量基本匹配。 修改口语发音的至少一个特征,以便当现有语音质量基本上不符合期望的语音质量时,将口语发音的现有语音质量改变为所需语音质量。 讲话话语以期望的语音质量呈现给预期的接收者。
