Does the speech service allow automating the training of a custom speech model through powershell?

Question

I would like to run training for a custom speech model but I want to do it through an automated pipeline instead of through the Speech Studio in Azure. Are there any apis that can be used to do this?
I would prefer to do this in powershell since all of our pipelines are written using powershell.
The documentation for Speech Service talks about a speech service cli but I do not have the authority to install that on our agents.

Hello Dan Pham,

Welcome to the Microsoft Q&A and thank you for posting your questions here.

Regarding your explanation, you would like to automate the training of a custom speech model through PowerShell.

Absolutely, you can automate the training of a custom speech model using PowerShell with the Azure Speech service. This is an example of steps to take, use the links for more detailed steps and code snippet:

#   Set Up Configuration
   spx --% config @key --set SpeechSubscriptionKey
   spx --% config @region --set SpeechServiceRegion
#   Create a Custom Speech Project
   spx --% csr project create --name "ProjectName" --language "en-US" --description "Description" --output url "@project.txt"
#   Upload Datasets for pronunciation data
     spx --% csr dataset upload --name "pronunciation_data" --description "data for pronunciation model" --data .\pronunciation.txt --kind Pronunciation --project "@project.txt" --output url "@dataset.pm.txt"
#   For language model adaptation
     spx --% csr dataset upload --name "language_model_data" --description "data for language model adaptation" --data .\language_model.txt --kind Language --project "@project.txt" --output url "@dataset.lm.txt"
#    For evaluation data
     spx --% csr dataset upload --name "test_data_1" --description "Test data for evaluation" --data .\test_data_1.zip --kind Acoustic --project "@project.txt" --output url "@dataset.test1.txt"
#   Check Dataset Status
   spx --% csr dataset status --dataset "@dataset.pm.txt" --wait
#   Train the Custom Model
   spx --% csr model train --project "@project.txt" --datasets "@dataset.pm.txt,@dataset.lm.txt" --output url "@model.txt"
#   Evaluate the Model
   spx --% csr model evaluate --model "@model.txt" --dataset "@dataset.test1.txt" --output url "@evaluation.txt"

These commands help automate the process of creating projects, uploading datasets, training models, and evaluating them https://github.com/Azure/custom-speech-stt/blob/main/automate.md and https://learn.microsoft.com/en-us/azure/ai-services/speech-service/how-to-custom-speech-train-model
