" summary

Shows how to configure iOS audio sessions to avoid glitches (use AVAudioSession category: playback/record/playAndRecord, choose ducking or mix options, handle interruptions) and how to make speech work with a few lines of code (AVSpeechSynthesizer + AVSpeechUtterance including voice, rate, pre/post delays and phonetic overrides). Covers SFSpeechRecognizer limits (per‑day and per‑app quotas, ~1 minute online chunks), permission requirements, offline recognition on A9+ devices when language packs exist, and practical workarounds for iOS 13.x bugs.
