Emacsvox speaks movement and command results. Integrations present information in meaningful units such as messages, search results, tables, source code, and Web pages. Voices can distinguish headings, links, comments, and other text; auditory icons and tones can identify events without adding words. Pronunciation dictionaries correct names and terms globally or for a mode or file.
Notice these distinctions before changing them. Compare structural voices in Hear Structure With Voice Lock. Aural Presentation explains speech, sounds, rules, and reusable voice settings in detail.
