The problem Pitch Perfect solves

Natural language is the lowest-friction interface for humans — no tutorials, no screens, no hurdles. Over 65% of users prefer voice for its hands-free speed and simplicity (Deloitte, 2022). But while voice control is intuitive, voice alone is not identity.

As AI agents increasingly act on our behalf — executing trades, authorizing payments, or routing cross-chain assets — ensuring the authenticity of the speaker becomes critical. Without an embedded identity layer, voice-controlled systems are prone to:

• 🎭 AI impersonation
• 🧠 Contextual spoofing
• 🔓 Unauthorized delegation of agentic tasks

We’re entering a new paradigm where speech is not just input, but intent — and that intent must be verifiable.

Our Solution

PitchPerfect introduces Beca. An identity-aware, voice-controlled AI agent for Web3 wallets.

Powered by ElizaOS & CCIP. Beca enables users to delegate actions or trigger customizable intents without trading off user trust or experience.

🔊 Voice becomes the controller of intent, not the signer of transactions.

• plugin-voice uses Microsoft WavLM to generate speaker embeddings and perform cosine similarity checks for identity.
• Beca Agent acts as the central orchestrator: all voice messages are sent here, where they’re dispatched to plugins for a specific action
• plugin-ccip links the voice intent with chain actions, such as asset transfers or portfolio analytics across multiple chains.
• sendToEVM() - Standard CCIP to supported EVM chain
• sendToAvalancheSubnet() - CCIP → Avalanche → Teleporter → Subnet
• sendToSolana() - CCIP to Solana/SVM wallets

Challenges I ran into

By design, shared storage for voice profiles raised a little concern because calculating similarities across a large number of profiles after each command may be exhaustive and less user-friendly.

To avoid that, we implemented a mechanism where session IDs tied to the client device/browser are synced with the ElizaOS runtime, allowing each vector filtering and matching without loading all profiles into memory.
