Retrieving full voice transcript via Speech and Text Analytics API

Is there a clean way to retrieve the full conversation transcript (voice-to-text) via the Speech and Text Analytics API? I am trying to fetch the complete text for a specific interaction ID using the Genesys Cloud Python SDK. My current approach hits the /api/v2/analytics/conversations/summary endpoint but only returns metadata, not the actual transcript text.

Here is the code snippet I am using:

response = api_client.get_analytics_conversations_summary(interaction_id=inter_id)

The response payload contains segments but lacks the text field for voice channels. I see transcript objects in the docs but no clear method call to fetch them. Is there a separate endpoint or parameter I am missing to get the raw text?
