Noise cancellation

[BigVeila]

I wonder if the iOS SDK supports a noise reduction feature. Currently, I am using the STT feature, and the Azure is recognize other sounds (5 meters from the mic).

@lucianopa-msft could you weigh in?

Hey @BigVeila,
We do have a support for noise suppression in our calling SDK, you can refer to Add audio quality enhancements to your audio calling experience where you can apply a levels of noise suppression through audio options in a call.
Example:

let outgoingAudioOptions = OutgoingAudioOptions()
let filters = OutgoingAudioFilters()
filters.noiseSuppressionMode = NoiseSuppressionMode.high
outgoingAudioOptions.audioFilters = filters

And apply to call options :)

@lucianopa-msft It seems like what you’re referring to is for calls. Currently, I’m only using Speech To Text, and I can not apply for SPXPushAudioStream,... From what I researched, there is a feature called Microsoft Audio Stack (MAS), but it only supports C# and Java.

Oh so you are not using AzureCommunicationCalling SDK, you just want speech to text in any Azure SDK? It is that the question?
Can you elaborate more on your scenario which Azure SDK are you using, which version and how are you getting STT feature?

This doesn't look like a AzureCommunicationCalling SDK issue, so should it be transferred to some other Azure SDK?

Closing as this is not a supported feature of the SDK.
