Fields

pitch: Option<PitchRange>

pitch: the baseline pitch for the contained text. Although the exact meaning of “baseline pitch” will vary across synthesis processors, increasing/decreasing this value will typically increase/decrease the approximate pitch of the output. Legal values are: a number followed by “Hz”, a relative change or “x-low”, “low”, “medium”, “high”, “x-high”, or “default”. Labels “x-low” through “x-high” represent a sequence of monotonically non-decreasing pitch levels.

contour: Option<PitchContour>

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.

range: Option<PitchRange>

the pitch range (variability) for the contained text. Although the exact meaning of “pitch range” will vary across synthesis processors, increasing/decreasing this value will typically increase/decrease the dynamic range of the output pitch. Legal values are: a number followed by “Hz”, a relative change or “x-low”, “low”, “medium”, “high”, “x-high”, or “default”. Labels “x-low” through “x-high” represent a sequence of monotonically non-decreasing pitch ranges.

rate: Option<RateRange>

a change in the speaking rate for the contained text. Legal values are: a non-negative percentage 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 the value is a non-negative percentage it acts as a multiplier of the default rate. For example, a value of 100% means no change in speaking rate, a value of 200% means a speaking rate twice the default rate, and a value of 50% 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.

duration: Option<TimeDesignation>

duration: a value in seconds or milliseconds for the desired time to take to read the contained text. Follows the time value format from the Cascading Style Sheet Level 2 Recommendation [CSS2], e.g. “250ms”, “3s”.

volume: Option<VolumeRange>

the volume for the contained text. Legal values are: a number preceded by “+” or “-” and immediately followed by “dB”; or “silent”, “x-soft”, “soft”, “medium”, “loud”, “x-loud”, or “default”. The default is +0.0dB. Specifying a value of “silent” amounts to specifying minus infinity decibels (dB). Labels “silent” through “x-loud” represent a sequence of monotonically non-decreasing volume levels. When the value is a signed number (dB), it specifies the ratio of the squares of the new signal amplitude (a1) and the current amplitude (a0), and is defined in terms of dB:

Trait Implementations

impl Clone for ProsodyAttributes

fn clone(&self) -> ProsodyAttributes

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProsodyAttributes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ProsodyAttributes

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for ProsodyAttributes

fn eq(&self, other: &ProsodyAttributes) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ProsodyAttributes

fn partial_cmp(&self, other: &ProsodyAttributes) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
