i am using nuance dragon mobile sdk for iPhone, for using text to speech.
The readed text is a little bit to fast and i want to make it slower, so the user can learn the words. My aim is to slow down the text a bit. That works very fine with SSML and prosody tag, see this code:
<prosody rate="slow">This is the text which is spoken slow,
but the voice sounds distorted/warped/ghastly</prosody>
The voice sounds distorted, warped and ghastly.
Do you understand what i mean?
What can i do to get a clear voice but slow speaked text?

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.
