我正在使用iPhone的 nuance dragon mobile sdk 来使用文字转语音。
readed文本有点快,我想让它变慢,所以用户可以学习这些单词。我的目标是减慢文本的速度。使用SSML和韵律标签可以很好地工作,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>
声音扭曲,扭曲和可怕 你明白我的意思吗? 我该怎么做才能获得清晰的声音但缓慢的语音文字?

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.
