Meet Four Speech
🎙️ Meet Four Speech
Four Speech is a voice-native execution framework that transforms natural language into verifiable, on-chain smart contract transactions. Each request originates as a spoken command, is parsed and validated via AI orchestration, and culminates in BSC-native execution governed by wallet-based authorization and deterministic logging.
The architecture consists of a modular Voice-to-Contract (V2C) stack that combines real-time transcription, large language model (LLM) parsing, domain-specific transaction synthesis, and programmable policy enforcement — all embedded within a non-custodial, user-controlled runtime.
When a user speaks, the Speech Gateway ingests voice input, transcribes it in real-time, and dispatches the text through the Semantic Intent Parser. The result is a structured execution graph: containing the action type, token metadata, gas rules, slippage caps, and transaction destination. A confirmation prompt is issued, and — upon user approval — the transaction is signed via MetaMask or WalletConnect and sent to the BNB mainnet.
Each step in the V2C pipeline is zero-retention, rule-enforced, and logged in a Merkle-bound Command Ledger, allowing downstream agents or dashboards to reconstruct action provenance and compliance events.
🧩 Core Capabilities
Voice-to-Contract Runtime
Spoken input is transcribed, parsed, and resolved into ABI-aligned payloads with typed parameter safety.
Wallet-Gated Execution
All transactions are signed by the user’s wallet using EIP-712 or 1559, enforcing self-custody and non-repudiation.
Intent Policy Layer
Optional JSON/WASM-based filters inspect commands for forbidden token pairs, unsafe protocols, or malicious amounts.
Deterministic Logging
Each command’s execution path (voice → TX) is hashed and chained into a local Merkle ledger.
Modular Command Registry
Each supported function (e.g., swap, stake, claim) is registered with its signature, type schema, and safety rules.
Future Multi-Chain Relay
While Phase 1 targets EBSC, outputs will be compatible with Arbitrum, Ethereum, Optimism, and EVM Layer-2s.
🤖 Voice-Native Agents on Speech AI
While Speech AI executes individual commands securely, the Speech Agent Framework enables developers to compose them into persistent, autonomous agents that can converse, confirm, and act on-chain — all via voice.
Command Pack Modules
Each voice-enabled “skill” is a callable V2C command with pre-bound safety logic.
Session Orchestrator
Chains skills into multi-step actions (e.g., “Buy then stake”), preserving user context.
Command Manifest
JSON or YAML configuration describing intent triggers, TX routes, slippage settings, and fallback flows.
Multi-Step Execution
Users can initiate voice flows like: “Swap 100 USDC to ETH and stake it on Aave.”
Hot-Swap Commands
New voice commands and model updates can be deployed live without breaking runtime.
🧪 Example Voice-Driven Workflows
Spot Trade
“Buy 0.1 ETH” → Confirm
Signed swap TX via Uniswap V3
Staking Flow
“Stake my ETH for rewards”
Stake into validator or LST contract
Portfolio Check
“What is my USDC balance?”
Reads ERC-20 balances via Web3 call
Combined Action
“Swap and Stake 50 USDT”
Multi-step TX: router + stake contract
🔐 Why Use Speech AI?
Auditable Natural Language Interface – All user commands and execution logic are traceable, human-readable, and linked to wallet signatures.
DeFi Accessibility Layer – Removes need for UIs, typing, or code. Just speak and confirm.
Modular & Non-Custodial – Runs entirely through user wallets; no custody, no third-party execution risk.
Future-Proof Interface Layer – Designed to integrate with agent platforms, AI agents, and autonomous financial apps.
With the Voice-to-Contract engine ensuring deterministic, rule-bound transactions, and the Agent Framework unlocking composable voice workflows, Speech AI delivers a secure, modular, and accessible execution layer for the voice-first future of decentralized finance.
