How The Demo Works
-
The Web Speech API is used to convert text to speech.
-
When a chunk of text is ready it is sent to our process api:
http://localhost:8091/process/ -
The text is forwarded to Amazon Comprehend and the result is returned to the dashboard.
-
Highcharts is used to create a visual representation of the sentiment and sentiment history. Any key phrases are formatted and displayed in the text area below the charts.
