Verdict

The call

The clearest difference is ads: Speech Central at none against Audibly's shown. Speech Central also leads on ratings volume (1.6K vs 4) and update cadence (every 9 days vs every 3 weeks). Audibly's advantage is review sentiment (100% vs 69%) and rating (5.0 vs 4.6). On price, in-app purchases and monetization model there is nothing between them.
