Example
SpeechSynthesisReadText("WINDEV is great!")
Syntax
<Result> = SpeechSynthesisReadText(<Text> [, <Locking>])
<Result>: Integer
  • Identifier associated with the reading,
  • 0 in case of failure. The ErrorOccurred variable is set to True if an error occurs. To find out the error details, use ErrorInfo.
<Text>: Character string (with quotes)
Text to read.
<Locking>: Optional boolean
  • True: the function is run in locking mode. The code following the call to the function will be run once the entire text is read or when the function fails. An hourglass will be displayed during the read operation. Use NextTitle to customize the message displayed by the hourglass.
  • False (default value): the function is run in non-locking mode. The code following the call to the function will be run as soon as the reading of the text starts or when the function fails.
<Result> = SpeechSynthesisReadText(<Text> [, <Locking>])
<Result>: Integer
  • True if the text was read (locking mode) or if the text was added to the reading queue (non-locking mode),
  • False in case of failure. The ErrorOccurred variable is set to True if an error occurred. To find out the error details, use ErrorInfo.
<Text>: Character string (with quotes)
Text to read.
<Locking>: Optional boolean
  • True: the function is run in locking mode. The code following the call to the function will be run once the entire text is read or when the function fails. An hourglass will be displayed during the read operation. Use NextTitle to customize the message displayed by the hourglass.
    Versions 21 and later
    iPhone/iPad This runtime mode is not available.

    iPhone/iPad This runtime mode is not available.
  • False (default value): the function is run in non-locking mode. The code following the call to the function will be run as soon as the reading of the text starts or when the function fails.
Remarks
  • AndroidAndroid Widget The functions for speech synthesis are available for the devices running Android version 1.6 or later (api level 4).
    A fatal error occurs if the function is used with an earlier system version.
    To find out the version of the Android system on which the application is run, use SysAndroidVersion.
  • Versions 21 and later
    iPhone/iPad The functions for speech synthesis are available for the devices running iOS version 6 or later. The speech synthesis does not operate on the iOS 8 emulators.
    New in version 21
    iPhone/iPad The functions for speech synthesis are available for the devices running iOS version 6 or later. The speech synthesis does not operate on the iOS 8 emulators.
    iPhone/iPad The functions for speech synthesis are available for the devices running iOS version 6 or later. The speech synthesis does not operate on the iOS 8 emulators.
  • AndroidAndroid Widget If no engine for speech synthesis is installed on the device, its download will be automatically proposed.
  • If a new read operation is triggered while another read operation is in progress, the new read operation will start once the first one is over.
    To find out whether a reading is in progress on the engine for speech synthesis, use SpeechSynthesisInProgress.
    To stop the current read operations, use SpeechSynthesisStop.
  • To define the parameters that will be used by the engine for speech synthesis (language, reading speed, etc.), use SpeechSynthesisInitialize.
    If the parameters of speech synthesis have not been defined by SpeechSynthesisInitialize, the default parameters will be used and the language for text reading will be the first language available for the engine of speech synthesis according to the following sequence:
    • Language of the application (default language or language defined by Nation),
    • Language of device,
    • English,
    • Default language of engine for speech synthesis.
  • To read the content of a text file, use SpeechSynthesisReadFile.
  • AndroidAndroid Widget To define the volume of reading, use VolumeModify associated with the volumeMusic constant.
  • Caution: SpeechSynthesisReadText does not instantaneously read the text when the mobile device is in standby mode. In this case, you can:
    • prevent from going in standby mode with SysStandby.
    • AndroidAndroid Widget use a persistent thread (ThreadPersistent) in order for the application to continue to run even during the standby mode.
