What This Project Does

Voice to Trade Binance Whisper is a voice trading bot for Binance that lets you place crypto trades using spoken commands.

Instead of manually clicking through exchange interfaces, you can say commands like:

• buy 0.5 BTC at market
• sell 1 ETH at limit 3500
• close my BTC position

This project is built for:

• Binance traders who want faster execution
• developers building voice-controlled trading tools
• traders testing hands-free crypto workflows
• users who want local speech-to-trade support with optional offline transcription

🧠 How Voice-to-Trade Works

Most traders lose 2–4 seconds per entry clicking through interfaces. At 20 trades a day, that's compounding latency you never get back.

This utility closes that gap with a three-stage pipeline:

╔══════════════════╗     ╔═══════════════════════╗     ╔══════════════════════╗ ║  MICROPHONE INPUT ║────▶║  WHISPER STT ENGINE    ║────▶║  INTENT PARSER       ║ ║                  ║     ║  (local or API mode)   ║     ║  side / symbol /     ║ ║  "Buy 0.5 BTC    ║     ║                        ║     ║  size / order type   ║ ║   at Market"     ║     ║  ~300ms transcription  ║     ║                      ║ ╚══════════════════╝     ╚═══════════════════════╝     ╚══════════╦═══════════╝                                                                    │                                           ╔════════════════════════▼═══════════╗                                           ║  BINANCE API EXECUTOR              ║                                           ║  POST /api/v3/order                ║                                           ║  → confirmed fill in <800ms total  ║                                           ╚════════════════════════════════════╝

You speak. The order is placed. The parser handles natural phrasing — "buy half a bitcoin market", "short 200 USDT ETH limit 3200", "close my BTC position" — without rigid command syntax.

⚡ Key Features of the Binance Whisper Voice Trading Engine

• Natural language command parsing — no rigid syntax to memorize; handles fractional quantities, ticker aliases, and order type variations
• Whisper local mode — run the STT engine fully offline; your voice audio never leaves your machine
• Paper trading mode — dry-run every command against live Binance prices with zero capital risk
• Real-time audio feedback — spoken confirmation of parsed intent before execution (optional, configurable)
• Hot-reload config — swap API keys, trading pairs, and risk limits without restarting the session
• Execution log — timestamped JSON log of every transcript, parsed intent, and API response for audit trails

🆚 How This Compares to Other Binance Trading Tools

| Tool / Approach | Voice Input | Natural Language | Local STT | Paper Mode | Latency (approx.) | Cost | |---|---|---|---|---|---|---| | voice-to-trade-binance-whisper | ✅ | ✅ | ✅ Optional | ✅ | ~700ms | Free / open | | Binance Web UI (manual) | ❌ | ❌ | — | ❌ | 3–6s (human) | Free | | TradingView Alerts → Webhook | ❌ | ❌ | — | ⚠️ Limited | 1–3s | $15–60/mo | | 3Commas / Pionex bots | ❌ | ❌ | — | ✅ | 1–4s | $29+/mo | | Custom keyword-command scripts | ⚠️ Rigid | ❌ | ✅ | Varies | Varies | DIY time | | Cloud STT + Binance webhook | ✅ | ⚠️ | ❌ | ❌ | 1.5–3s+ | $0.006/15s |

The gap: Every existing voice-adjacent solution either requires rigid command syntax, routes your audio through a cloud provider, or doesn't connect to execution at all. This project is the only open pipeline that goes from natural speech → Binance fill with a local model option.

🔧 Installation — Binance Whisper Voice Trading Bot

Requirements: Python 3.10+, PortAudio (for PyAudio), ffmpeg

Step 1 — Clone the repository

git clone https://github.com/leionion/voice-to-trade-binance-whisper.git cd voice-to-trade-binance-whisper

Step 2 — Create a virtual environment and install dependencies

python -m venv venv source venv/bin/activate        # Windows: venv\Scripts\activate pip install -r requirements.txt

Step 2b — Install PortAudio (required for microphone mode)

# Ubuntu/Debian: sudo apt install portaudio19-dev 
macOS:  brew install portaudio
 
Windows: PyAudio wheel usually includes it
 pip install PyAudio

Step 3 — Install Whisper and ffmpeg

pip install openai-whisper 
macOS:  brew install ffmpeg
 
Ubuntu: sudo apt install ffmpeg
 
Windows: https://ffmpeg.org/download.html

Step 4 — Configure credentials (optional for paper mode)

cp config.example.yaml config.yaml 
Option A: Edit config.yaml
 
Option B: Use .env (recommended for keys):
 cp .env.example .env 
Add OPENAIAPIKEY for Whisper API mode, BINANCEAPIKEY/SECRET for live trading

| Key | When needed | Env var | |-----|-------------|--------| | Binance API | Live trading only | BINANCEAPIKEY, BINANCEAPISECRET | | OpenAI API | Whisper cloud mode (whisper.mode: api) | OPENAIAPIKEY | | Paper mode | None | — |

Step 5 — Start in paper trading mode (always start here)

python main.py --mode paper

Test without a microphone:

python main.py --mode paper --transcript "buy 0.001 btc at market"

python main.py --mode paper --file your_recording.wav

⚠️ --mode paper runs all commands against live prices but places no real orders. Verify parsing is correct for your speech patterns before switching to --mode live.

🔒 Want the Full Private Build?

The public repo ships the core pipeline. The private build is for traders who need this to actually work in a live session.

What's in the private build that isn't here:

• Multi-pair session memory — "add 100 to the ETH position" works because it remembers what you're holding
• Confidence gate — orders with low transcription confidence are held and read back; you approve or cancel by voice
• Exchange-agnostic router — same voice commands, routes to Binance / Bybit / OKX based on config
• Wake-word activation — always-on listening with a trigger phrase so the mic isn't continuously recording
• Risk layer — per-symbol max exposure, daily loss limit, and portfolio concentration checks before any order fires
• Pre-built intent library — 40+ tested command phrasings across 4 accents to reduce parse errors

Who this is for:

| Profile | Why this matters to you | |---|---| | Active Binance day traders doing 10+ trades/session | Keyboard/click latency adds up; voice removes it entirely | | Algo traders backtesting new execution workflows | Paper mode + JSON logs give you a clean data layer to build on | | Developers building voice-first trading interfaces | The intent parser and audio pipeline are the hard part — this solves it | | Traders with accessibility needs or multi-monitor setups | Hands-free execution is a workflow change, not a gimmick |

How to reach me:

GitHub: @leionion

When you reach out, mention three things:

• How you currently execute trades on Binance (manual, alerts, bot)
• Which part of the private build matters most to you
• Whether you need paper-only access first or you're ready to test live

The gap between this repo and the private build isn't time. It's features that only make sense once you've watched a miscaptured voice command try to place an order. The private build was built after that happened.
