Strengths & caveats

DeepgramLow, clean per-character price (unchanged at $0.030/1K, $0.027/1K at Growth tier) aimed at voice-agent/IVR workloads with streaming and a large English voice catalog (40+ EN voices). Narrow language coverage, confirmed in the docs at 7 (EN, ES, NL, FR, DE, IT, JA). Independent Coval TTFA improved from 313ms to 293ms P50 — second-best in this table behind Cartesia — but still far off the vendor's '90ms' claim. Aura-2 itself is unranked on the Speech Arena, so naturalness ELO is left null; Deepgram's newer Flux TTS does appear but only at rank 59 (1054 ELO) and costs more at $0.045/1K after a free period ending 2026-09-12. No voice cloning.SpeechifyHighest-scoring row in this table on the Artificial Analysis Speech Arena (1240 ELO, rank 3 of 99), with low measured latency (398 ms P50 in the Coval capture, 3.4% WER), flat per-character pricing, and streaming, SSML and voice cloning from the entry tier; 50K characters/month free. Plan-bundled pricing: the $10/1M rate is the Starter overage (Pro $8/1M, Scale $6/1M), so effective cost depends on tier and is marked not directly comparable; the 30+ language count is a platform-wide claim rather than a Simba-specific spec, and the production ecosystem is younger than ElevenLabs'.
