Our plugins ReadAloud, EnglishCentral and our soon to be released auto grading speaking question can evaluate the content or the quality of a student's speaking for you.
Cloud Poodll activities can transcribe audio and video, and can even create subtitles. Now its possible to review hours of student speaking by reviewing their transcripts.
Using Poodll you can leave audio (or video) feedback on student assignments. Its fast and students appreciate the personal touch.
Text to Speech
Human narration for course content is ideal, but text to speech audio can save you time. It is easy to create, copy, edit and alter. Poodll has a range of TTS voices and great Moodle integration.
