The on-device AI dictation, which Apple says delivers a major boost in accuracy, is available only on select hardware including iPhone 17 Pro, iPhone Air, second-generation Vision Pro, and iPads and Macs with M4 or M3 chips and at least 12 GB RAM. Users can enable the feature by navigating to Settings, General, Keyboards, and toggling \"Advanced Dictation Preview.", "body_md": "# iOS 27 Beta 1 Ships With Advanced Dictation Off By Default\n\nAccording to 9to5Mac, the new on-device AI dictation feature in **iOS 27 beta 1** is disabled by default on updated devices. 9to5Mac reports the feature, called **Advanced Dictation Preview**, uses the AFM Core Advanced on-device model and is available only on select hardware: **iPhone 17 Pro**, **iPhone Air**, second-generation **Vision Pro** (M5), **iPad** with **M4** or later and at least **12 GB RAM**, and **Mac** with **M3** or later and at least **12 GB RAM**. 9to5Mac also notes Apple said the new technology delivers \"as a major boost in accuracy.\" 9to5Mac publishes a simple enablement path: Settings -> General -> Keyboards -> toggle \"Advanced Dictation Preview.\" 9to5Mac reports the feature runs fully on-device and works offline.\n\n### What happened\n\nAccording to 9to5Mac, the first developer beta of **iOS 27** ships with the new **Advanced Dictation Preview** switched off by default. 9to5Mac reports the preview uses the on-device AFM Core Advanced model and that Apple said the technology delivers \"as a major boost in accuracy.\" 9to5Mac lists supported hardware as **iPhone 17 Pro**, **iPhone Air**, second-generation **Vision Pro** (M5), **iPad** (M4) or later with at least **12 GB RAM**, and **Mac** (M3) or later with at least **12 GB RAM**. 9to5Mac documents the enablement steps: Settings -> General -> Keyboards -> toggle \"Advanced Dictation Preview.\" 9to5Mac states the system-wide dictation improvements also affect Siri and run without a network connection.\n\n### Technical details\n\nEditorial analysis: The published coverage describes this as an on-device AFM Core Advanced model powering both transcription and expressive voices, emphasising higher accuracy and local execution. For practitioners, on-device LLMs like this typically trade model size and performance against thermal, memory, and power constraints on target silicon.\n\n### Context and significance\n\nReporting frames this as part of a broader move by platform vendors toward on-device AI for latency, privacy, and offline capability. Comparable releases from other OS vendors have gated advanced features to newer hardware and RAM thresholds during early betas to limit user impact while collecting feedback.\n\n### What to watch\n\nEditorial analysis: Observers will watch whether Apple leaves Advanced Dictation off by default throughout the beta cycle or enables it for wider hardware at public release. Practitioners integrating speech or assistant features should note the device and RAM requirements reported by 9to5Mac when estimating where on-device parity with cloud transcription will be achievable.\n\n## Scoring Rationale\n\nThis is a notable product update for iOS developers and ML practitioners tracking on-device LLM deployment. It is not a frontier-model release, but it signals mainstreaming of local LLM-powered features and hardware gating that affect app compatibility and testing.\n\nPractice interview problems based on real data\n\n1,500+ SQL & Python problems across 15 industry datasets — the exact type of data you work with.\n\n[Try 250 free problems](/problems)", "url": "https://wpnews.pro/news/ios-27-beta-1-ships-with-advanced-dictation-off-by-default", "canonical_source": "https://letsdatascience.com/news/ios-27-beta-1-ships-with-advanced-dictation-off-by-default-64343e7a", "published_at": "2026-06-12 18:56:17.568017+00:00", "updated_at": "2026-06-12 18:56:21.594465+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-products", "natural-language-processing", "ai-tools"], "entities": ["9to5Mac", "Apple", "iOS 27", "Advanced Dictation Preview", "AFM Core Advanced", "iPhone 17 Pro", "iPhone Air", "Vision Pro"], "alternates": {"html": "https://wpnews.pro/news/ios-27-beta-1-ships-with-advanced-dictation-off-by-default", "markdown": "https://wpnews.pro/news/ios-27-beta-1-ships-with-advanced-dictation-off-by-default.md", "text": "https://wpnews.pro/news/ios-27-beta-1-ships-with-advanced-dictation-off-by-default.txt", "jsonld": "https://wpnews.pro/news/ios-27-beta-1-ships-with-advanced-dictation-off-by-default.jsonld"}}
