Speech transcription is at the heart of Poodll ReadAloud's automated evaluation features. Poodll uses more than one transcription system. Poodll will do its best to choose the best system automatically for the browser, activity type and passage language. But there are several options which you can use to customize this behaviour.


Passage language



This is by far the most important setting. The default setting can be altered in the Poodll ReadAloud admin settings. If not explicitly set, it will default to US English. Poodll will attempt to transcribe the users speech into text using the passage language. 


Just beneath the passage language is the TTS Voice setting. This does not affect speech transcription, but should at least be a voice of the same language as the Passage language. 


Line and Passage Transcriber



Poodll uses a combination of browser based recognition, 3rd party transcription services and Poodll own speech to text engine (Poodll STT). The default settings should work. But you may get more accurate, faster or more generous matching by selecting a different transcriber


Line Transcriber


This setting controls the transcriber used when doing line by line reading in "Practice" mode. 

Default (recommended)This will use browser based recognition on Google chrome and Poodll STT on other browsers. Browser recognition will also be extended to Safari and Edge browsers as it becomes reliable to do so.


Use Poodll STTPoodll STT is slower and more generous (ie will find fewer mistakes). It supports English, French, German and Spanish. And for other languages calls out to a third party subscription service.


Passage Transcriber


This setting controls the transcriber used when doing entire passage reading, either in "Shadow" or "Read" mode. 

Use Poodll STT (default)Poodll STT is faster then Strict STT and it is more generous (ie will find fewer mistakes). It supports English, French, German and Spanish. For other languages it falls back to Strict STT.


Use Strict STTStrict STT calls out to a third party subscription service. It is slower and can take 3-4 minutes for a result to be returned.
