Spark Voice Trader is a hands-free trading assistant that runs on your phone. You talk to it through Meta Ray-Ban glasses or the phone: "How's my Nvidia position, and is it near support?", "Show me next week's Nvidia puts", "Buy two of the second strike". It calls the right market tools, speaks a short natural answer, and drives the app for you: it opens the chart with the support line it just mentioned, the options chain on the strike it named, or a pre-filled order ticket. Orders are never placed by voice: you review the ticket and tap send. The agent is Meta's open-weight Llama 3.2 1B, fine-tuned with LoRA by distillation from Muse Spark: Spark answered thousands of trader questions with our tools through the Meta Model API, and we kept only the answers with correct tool calls. The model runs a closed loop: it picks the tools, code executes and checks them, and it writes an answer whose numbers are filled in by code, so it never speaks a number it made up. Conversation memory handles follow-ups like "what about its RSI". Inference runs on the phone: the fine-tuned model, quantized to under a gigabyte, generates every token on a Galaxy Z Fold, with on-device speech recognition and an on-device neural voice. Only the tool calls go over the network, to a service that plays the stock market. Results on 238 held-out trader questions: the Spark-trained 1B picks the right tools 90.8% of the time (89.9% right arguments), ahead of Muse Glimmer 30B (61.8% base, 77.7% trained on the same Spark traces), and answers in 0.68 s p50 versus 4.2 s. The phone build scores the same on tool choice. The adapter is public on Hugging Face: https://huggingface.co/leapsify/spark-voice-trader-llama-3.2-1b-lora
