Text to Speech Kubernetes¶

This page covers how to get the Text to Speech service running on OpenShift.

The files relating to this example can be found in the repository here

Deploy to OpenShift¶

1. Navigate to where the files from this repo have been cloned to your local machine and change to the speech/tts_kube directory

2. Create a new project on the cluster

   oc new-project demo-tts
   

3. Apply all the manifest files to your cluster

   oc apply -f <directory containing manifest files>
   

Testing the deployment¶

To test the speech to text container the curl utility can be used to submit requests, alter the URL to the route of the service on your cluster:

curl -k "https://tts-embed-demo-tts.apps.ocp.lab.home/text-to-speech/api/v1/synthesize" \
  --header "Content-Type: application/json" --data '{"text":"Hello world"}' \
  --header "Accept: audio/wav" --output output.wav

This used the default voice set in the configuration. You can also specify a different voice as part of the request, so long as the voice model was built into the runtime:

curl -k "https://tts-embed-demo-tts.apps.ocp.lab.home/text-to-speech/api/v1/synthesize?voice=en-GB_JamesV3Voice" \
  --header "Content-Type: application/json" \
  --data '{"text":"Hello! Isn''t it a wonderful day."}' \
  --header "Accept: audio/wav" \
  --output british-test.wav

Refer to the API reference for details of the requests that can be made
