Thoughts On Azure Microsoft.CognitiveServices.Speech and Xamarin.Forms

• I struggled using Stream... I could not get a good example or workaround for using Stream with Microsoft.CognitiveServices.Speech.
• The SDK has not been optimized for Xamarin and hence can be painfully slow.
• This service is pretty cool though 🙃
• Aand... Xamarin rocks!!! 😎

What went Well

• I was able to successfully implement speech-to-speech translation

What did not go so well

• I struggled using stream when sending speech, ended up using .wav files which can be quite slow 😪.
• My UI... It's not the best out there 😅
