Filters: SimpleSpeak text-to-speech

filter_simplespeak
A Moodle filter to provide speech synthesis (text-to-speech/ TTS) services for arbitrary text.
Maintained by: Nick a few years ago, in a leather jacket Nick Freear

A filter to provide speech synthesis (text-to-speech/ TTS) services for arbitrary text. Text such as [Speak] Hello world! [/Speak] is replaced with a button with the text as a label. Press the button, and the text is spoken!

This is beneficial, for example, when teaching younger children. And for accessibility to those with disabilities.

Requirements: tested with Moodle 1.9.7 and 2.0.2 (all Moodle 1.9.x and 2.0.x should work). Requires Javascript. Requires a TTS service - see Readme.

Uses:  jQuery (v1.3.2).

Installation

  1. Download and unzip the code files. Copy to the directory on the server, eg.
      /var/www/moodle/filter/simplespeak/
  2. Log in to Moodle as admin, visit `Site Administration | Modules | Filters | Manage Filters`. Scroll down and click on the icon for Simplespeak to enable it.
  3. Choose SimpleSpeak under Filters, and add a TTS service. Or set in config.php, eg.
    $CFG->simplespeak_service_url =
      'http://example.org/cgi-bin/espeak/getsound.pl?lang=!LANG&text=!TEXT';
    The string can contain two placeholders, !TEXT and optionally !LANG (language). This service can be local, or third-party - see Readme.
  4. Ensure that the directory $CFG->datarootis writeable by the Apache user, or create a writeable cache directory,
      $CFG->dataroot/simplespeak/cache/

Usage

Simple example. Enable the filter (admin). Then, type the following in a Moodle resource:

  [Speak] Hello world! [/Speak]

    Hi Nick
    Very strange. The same filter which works on Moodle 1.9.15, with the setting text of:
    http://translate.google.com/translate_tts?tl=en&q=!TEXT
    doesn't work in Moodle 2.5. I can't figure out why. Any ideas?

    Is there a way to change the font from what appears to be green comic sans to what appears on the rest of the page? I've been looking through the code, and I'm not seeing anything that jumps out at me for changing it. Any help would be appreciated!

    Hi,
    currently it supports only 100 chars with tag if it exceeds it not working. Is there any way to increase the chars?
