Plivo Configuration

Webhook URLs — paste these into Plivo Dashboard

Plivo Dashboard Setup:
1. Go to Plivo Console → Phone Numbers → your number → Configure
2. Under Call: set Answer URL = Voice Webhook above, method = POST
3. Under Message: set Message URL = SMS Webhook above, method = POST
4. Save, then upload your restaurant menu in the Menus tab

Speech Recognition (ASR)

✅ No Deepgram or Google ASR key needed.

Voice calls use Plivo's built-in <GetInput inputType="speech"> verb, which runs Google Speech-to-Text internally. Plivo returns the transcribed text as SpeechResult in the POST to your gather webhook. Billed as Plivo Speech Recognition — check your Plivo plan for included minutes.

SMS uses the caller's own text directly — no ASR needed.

Claude (Anthropic API) handles recommendation generation only, using the menu text and the caller's question. Set ANTHROPIC_API_KEY in /home/azureuser/work/recsys/.env.
