Question Answering Using Wolfram|Alpha
Speech recognition can open up new workflows for existing functionality. Build a question-answering machine that gets its input from recordings of spoken questions and leverages the Wolfram|Alpha knowledgebase.
Start with a spoken query.
Transcribe the spoken question with SpeechRecognize.
Send the query to WolframAlpha.
Get the spoken result from Wolfram|Alpha and synthesize it using SpeechSynthesize.
