Best Fish Audio alternatives for text-to-speech in 2026 (including ElevenLabs)

Fish Audio’s alternatives are assessed primarily for production text-to-speech and voice-agent use, where its lower listed price of $15 per million UTF-8 bytes may be offset by byte-based billing for accented text, concurrency limits tied to prepaid spending, US-default data handling, a 99% enterprise SLA, and security certifications still in progress. ElevenLabs is presented as a common choice for creators because of its voice features and broad language support, though its listed per-character pricing is higher, low-latency model language coverage is narrower, concurrency depends on subscription plans, and its free tier lacks commercial rights. AssemblyAI-TTS-1 is positioned for voice agents with $15 per million characters, no hard concurrency caps, US or EU processing, voice cloning, streaming controls for barge-in, compliance certifications, and benchmark claims of faster first audio and more accurate reading of codes and addresses than Fish Audio, while lacking Fish’s current emotion-control capability. Cartesia and Inworld offer telephony-oriented output and plan-based concurrency, while open-weight models such as Kokoro and Chatterbox provide self-hosting flexibility but require users to manage infrastructure and operations. The comparison recommends evaluating providers using real agent scripts, regional latency, peak-call behavior, and accuracy on details such as confirmation codes rather than relying only on headline pricing.
