Verdict
The clearest difference is price: Vocalize AI at Free against DSDir's $1.99. Vocalize AI also leads on iOS requirement (15.0 vs 17.0). DSDir's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). On in-app purchases and device support there is nothing between them.
