Method: RubySpeech::SSML::Prosody#contour

Defined in:
lib/ruby_speech/ssml/prosody.rb

#contour ⇒ Symbol

The actual pitch contour for the contained text.

The pitch contour is defined as a set of white space-separated targets at specified time positions in the speech output. The algorithm for interpolating between the targets is processor-specific. In each pair of the form (time position,target), the first value is a percentage of the period of the contained text (a number followed by “%”) and the second value is the value of the pitch attribute (a number followed by “Hz”, a relative change, or a label value). Time position values outside 0% to 100% are ignored. If a pitch value is not defined for 0% or 100% then the nearest pitch target is copied. All relative values for the pitch are relative to the pitch value just before the contained text.

Returns:
