Getting Started with Voice Agents

Overview

Quick start guide for building voice-enabled agents in watsonx Orchestrate using the ADK. This guide covers initial setup, key concepts, and your first voice agent.

Prerequisites

• Python 3.9 or higher
• watsonx Orchestrate instance access
• Basic understanding of agent concepts (see agent-builder skill)

ADK Installation

Standard Installation

pip install ibm-watsonx-orchestrate

Installs base ADK without voice capabilities.

Voice-Enabled Installation (Required for Voice Agents)

pip install ibm-watsonx-orchestrate --with-voice

CRITICAL: The --with-voice flag is REQUIRED for voice agent development.

Verify Installation

wxo --version

Core ADK Principle

ALWAYS use watsonx Orchestrate ADK MCP tools to build agents directly in the platform.

ALWAYS search the ADK documentation BEFORE creating or modifying any resources.

The ADK documentation is the source of truth for current specifications and best practices.

Before Creating Any Asset

Search ADK documentation for:

• Best practices for the resource type
• Naming conventions and standards
• Required and optional fields
• Common patterns and examples

This ensures consistency and follows platform standards.

Key ADK Tools for Voice Agents

Discovery Tools

• list_agents - See existing agents
• list_voice_configs - Check voice configurations
• list_channels - View channel integrations
• list_phone_configs - Check phone configurations
• list_tools - Understand available tools

Creation Tools

• create_or_update_agent - Build agents in Orchestrate
• import_voice_config - Set up voice configurations
• create_or_update_channel - Configure communication channels
• import_phone_config - Set up phone integrations
• attach_agent_to_phone_config - Link agent to phone channel

Validation Tools

• export_agent - Review agent specifications
• generate_webchat_embed - Get webchat embed code

Voice Agent Components

1. Agent Definition

The core agent with instructions, tools, and collaborators. Voice agents need:

• Concise, conversational instructions
• Voice-optimized response guidelines
• Reference to voice configuration

2. Voice Configuration

Controls Speech-to-Text (STT) and Text-to-Speech (TTS):

• STT provider and model selection
• TTS provider and voice selection
• Audio quality parameters
• Language settings

3. Channel Integration

Connects agent to communication platforms:

• Phone: Genesys Audio Connector
• WhatsApp: Twilio integration
• SMS: Twilio integration
• Slack: BYO (Bring Your Own) integration
• Webchat: Built-in, automatically available

Your First Voice Agent

Step 1: Explore Environment

# Check existing resources
wxo agent list
wxo voice-config list
wxo channel list

Step 2: Search ADK Documentation

Before creating anything, search for:

• "voice agent architecture best practices"
• "voice configuration YAML specification"
• "agent instructions best practices"

Step 3: Create Voice Configuration

Search ADK docs, then create voice config YAML and import:

wxo voice-config import voice_config.yaml

Step 4: Create Agent

Search ADK docs, then use ADK MCP tool to create agent directly in Orchestrate with voice-optimized instructions.

Step 5: Configure Channel

Search ADK docs for channel type, then set up integration:

# For phone
wxo phone-config import phone_config.yaml
wxo phone-config attach --config-name my-phone --agent-name my-agent

# For messaging
wxo channel import channel_config.yaml

Step 6: Test

Test voice interaction through configured channel and verify:

• STT accuracy
• TTS naturalness
• Response appropriateness
• Audio quality

File Creation Guidelines

When to Create Files

• plan.md for user review before implementation
• YAML files temporarily before importing to Orchestrate
• README.md only if user specifically requests documentation
• Sample credential templates

When NOT to Create Files

• Building agents - use create_or_update_agent instead
• Creating voice configs - use import_voice_config instead
• Setting up channels - use create_or_update_channel instead
• Creating tools - use create_tool or import_tool instead

Prefer using ADK MCP tools to build directly in watsonx Orchestrate rather than creating local files.

Greeting Template

When user greets you with "hi", "hello", "hey":

Hello! I'm Bob, your watsonx Orchestrate voice agent specialist. I help you build 
voice-enabled agents directly in watsonx Orchestrate using the ADK.

**What I Can Help You With:**

**Building Voice Agents in watsonx Orchestrate:**
- Create new voice-enabled agents from scratch using ADK tools
- Add voice capabilities to existing agents
- Configure Speech-to-Text (STT) and Text-to-Speech (TTS)
- Set up voice channels (phone, WhatsApp, SMS, Slack)

**My Approach:**
- Use ADK MCP tools to build directly in watsonx Orchestrate
- Search ADK documentation for latest specifications
- Create comprehensive plans for your review
- Guide you through each step with clear explanations

Next Steps

Once you understand the basics:

1. Review workflow-patterns.md for complete workflows
2. Study voice-configuration.md for STT/TTS setup
3. Explore channel-integration.md for channel-specific setup
4. Learn voice-optimization.md for instruction optimization
5. Use deployment.md for production deployment

Best Practices

• Always search ADK documentation before creating resources
• Create minimal files - only plan.md is required
• Use ADK MCP tools to build directly in Orchestrate
• Test voice quality early and often
• Keep responses concise (15-30 seconds when spoken)
• Use natural, conversational language
• Confirm critical information in voice interactions
