FAQ
What is LLMVoice?
LLMVoice is a technical showcase for iOS 26 speech recognition and on-device AI. It utilizes the MLX Swift framework to run open-source language models locally on Apple Silicon, offering features like real-time voice transcription and AI-powered summarization.
What are the system requirements for LLMVoice?
LLMVoice requires iOS 26.0+ (or iPadOS 26.0+ for iPad). Apple Silicon is recommended for optimal performance. You will also need microphone and speech recognition permissions, and storage space for models ranging from 150MB to 500MB each.
Does LLMVoice require an internet connection?
LLMVoice is designed for 100% on-device processing, meaning audio never leaves your device and AI inference is local. An internet connection is only required for downloading AI models from Hugging Face; otherwise, it functions offline.
What AI models can I use with LLMVoice?
You can use Apple's built-in on-device foundation models for summarization on supported devices (iPhone 15 Pro or later). Additionally, LLMVoice supports several open-source models via MLX Swift, including Qwen2.5 (0.5B), Gemma 3 (1B), and Llama 3.2 (1B), all using 4-bit quantization for efficiency.
How does LLMVoice handle privacy?
LLMVoice prioritizes privacy by performing all processing on-device. Audio data is not collected or sent to the cloud, and there is no tracking or data collection involved, ensuring complete user privacy.
Is LLMVoice suitable for beginners?
While LLMVoice is built with modern Swift and SwiftUI, making it a great learning tool for developers, its primary audience is developers and early adopters exploring advanced iOS 26 and on-device AI capabilities. Beginners might find the technical nature challenging without prior Swift or AI knowledge.
How often is LLMVoice updated?
