Description

Conversational AI VoiceBots are helping businesses automate repetitive, time-consuming queries and are giving your team more time to tackle more complex, high priority strategic tasks, while still ensuring that the customers are engaged. Chatbots that take in voice input can ingest, analyze, interpret, and respond to customer inquiries, with the end goal of either being able to answer a customer’s question in real-time or being able to continue a textual exchange with the customer to clarify the question at hand.

In this code pattern, We will build a framework using which the user will be able send his/her queries over voice on whatsApp and get a reply from Watson Assistant. The query from the user is sent to the Watson Speech to Text service through a custom application. The output from the Watson Speech to Text service is then feed to Watson Assistant. Watson Assistant replies back to the user with an appropriate reply.

When you have completed this code pattern, you will understand how to:

  • Use Watson Speech to Text service.
  • Use Watson Assistant service.
  • Integrate WhatsApp with Watson services.
  • Handle queries sent over voice on WhatsApp.

Flow

architecture

  1. User sends a voice or text message in WhatsApp.
  2. The message is redirected to Twilio Programmable messaging service.
  3. Twilio redirects the message to the Voicebot Application deployed on IBM Cloud or OpenShift.
  4. If the user has sent a voice message, the Voicebot Application leverages Watson Speech to Text to transcribe the message into text.
  5. The text message is sent to Watson Assistant.
  6. Watson Assistant chatbot detects the intent and replies with response accordingly.
  7. The Voicebot Application triggers the Twilio Programmable messaging service with the response message.
  8. Twilio Programmable messaging service redirects the response message to WhatsApp.
  9. User will be able to view the response message on Whatsapp.
