Now that we are done with that, we can then go ahead and get coding. For translation, you can checkout the Speech SDK The API does not provide partial results. For batch transcriptions and custom speech use Speech to Text API v3.0 Requests cannot contain more than 60 seconds of audio. It is noteworthy that the speech to text rest API for short audio has several limitations which are: Since now we have our audio sample input sample.wav ,we can now go ahead to the transcribing bit. Select I have read and understood the noticesĬlick on Review create and we are good to go.Īs a guide, these are the settings I used however, you can go ahead and get creative with the names. Resource group: Create one with a unique name or an existing one Subscription: Enter your Azure subscription Click Create a resource and on the search bar, type Speech, click create and create a Cognitive service resource with the following settings: Open the Azure portal and sign in using your Microsoft account. We then proceed to create a cognitive resource group by following these steps: \\ 1. You can create a free Azure account here and if you have an account already, you can skip this step. We now proceed to process this and transcribe the audio we just recorded 3 House Keeping on Azureįirst we begin with some light housekeeping, i.e setting up a Cognitive Services resource in our Azure subscription. For now, we go by the saying: if it works, don’t touch it and implement this step to clear the audio instance object. I know this is not an elegant solution (more like tying duct tape around a leaking pipe )and i am actively looking for a better solution to fix this issue. After doing some research, I discovered that restarting the console clears the audio instance object therefore allowing for one to record audio multiple times with no issue. However, using this method proved to be cumbersome as it causes the console to freeze anytime you want to record audio for more than one time. From the audio package documentation, this is achieved by using the close(con,…) method, where con is the audioInstance object. On recording and saving the audio file to sample.wav, we have to clear the audio instance object audio_obj before proceeding to make the next recording. #Set our recording time rec_time <- 5 #Recording Samples <- rep( NA_real_, 44100 * rec_time) #Defining number of samples recorded print( "Start speaking") audio_obj <- record(Samples, 44100, 1) #Create an audio instance with sample rate 44100 and mono channel wait( 6) rec <- audio_obj $data # get the recorded data from the audio object #Save the recorded audio file.create( "sample.wav") #gets created in your current working directory save.wave(rec, "Insert_path_to_sample.wav_here")
