如何用SSML减慢文本到语音 – 语音听起来失真/变形/可怕

我正在使用细微的龙手机sdk为iPhone，使用文字发言。
被阅读的文本有点快，我想让它慢一点，所以用户可以学习这些单词。 我的目标是放慢文本。 这对于SSML和韵律标签来说非常好，请参阅以下代码：

<prosody rate="slow">This is the text which is spoken slow, but the voice sounds distorted/warped/ghastly</prosody> 

声音听起来扭曲，扭曲和可怕 。
你明白我的意思吗？
我能做些什么来获得一个清晰的声音，但慢文字 说话 ？

从这里取： http : //www.w3.org/TR/speech-synthesis/#S3.2.4

 rate: a change in the speaking rate for the contained text. Legal values are: a relative change or "x-slow", "slow", "medium", "fast", "x-fast", or "default". Labels "x-slow" through "x-fast" represent a sequence of monotonically non-decreasing speaking rates. When a number is used to specify a relative change it acts as a multiplier of the default rate. For example, a value of 1 means no change in speaking rate, a value of 2 means a speaking rate twice the default rate, and a value of 0.5 means a speaking rate of half the default rate. The default rate for a voice depends on the language and dialect and on the personality of the voice. The default rate for a voice should be such that it is experienced as a normal speaking rate for the voice when reading aloud text. Since voices are processor-specific, the default rate will be as well.
