Powershell can speak, but can it write if i speak?

Following is the way to make powershell to speak.

Add-Type -AssemblyName System.Speech
$synthesizer = New-Object -TypeName System.Speech.Synthesis.SpeechSynthesizer
$synthesizer.Speak('Hey, I can speak!')

Actually i would like to do opposite. If i speak , can powershell convert it into letters.

If i say in my sound recorder "Hey, I can speak", will it convert into text?

If possible please guide me how to achieve it?
