Speak
Speak[expr]
speaks a spoken representation of the expression expr.
Details and Options
- Speak["string"] speaks the text in
. - Speak[expr] works with mathematical expressions, programs, graphics, and other constructs.
- Speak[HoldForm[expr]] speaks the held form of expr, without evaluation.
- Speak attempts to produce naturally worded speech rather than literal representations of expression structure.
- Speak produces sound using your computer's operating system.
- SpokenString[expr] gives text for the speech generated by Speak[expr].
- The following options can be given:
-
"ArraySizeLimit" 10 maximal number of elements of an array or arguments of a function "DetailedGraphics" False controls the description of graphics primitives "ExpressionDepthLimit" 10 maximal depth of an expression allowed in the output "IncludeParentheses" False controls the delimiting of subexpressions "IntegerLimit" 10^10 maximal integer that will be given with all its digits "RealPrecisionLimit" 3 how many significant digits to include in approximate numbers "StringLengthLimit" 1000 maximal number of characters in strings and symbol names 
and 
control the size of all output expressions, including the representation of graphics.- The options controlling the size specify the level of complexity at which to begin eliding parts of the output rather than the exact count of elements in the output.
- Speak["str"] sends
to the speech engine. Speak[HoldForm["str"]] speaks a processed version of the string, affected by the options. - Speak[Unevaluated[expr]] also speaks the held form of expr.
- The text string that is sent to the speech engine on your computer system is given by SpokenString[expr, Options[Speak], "PostProcess"->False].
