如何使用SSML減慢文本到語音 - 語音聲音失真/變形/可怕

Question

我正在使用針對iPhone的細微差異龍移動sdk，用於使用文本到語音。
急速的文字是有點快，我想讓它變慢，所以用戶可以學的話。我的目標是慢一點文本。這工作很細跟SSML和韻律標籤，查看此代碼：

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

的聲音聽起來扭曲，扭曲和可怕。
你明白我的意思嗎？
我能做些什麼來獲得一個清晰的聲音但慢說的文字？

從這裏取：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.
