Deepgram
Deepgram is a developer speech platform best known for fast, cheap, accurate speech-to-text via its Nova model family, plus Aura text-to-speech and a voice-agent API. Pricing is pay-as-you-go per minute (Nova STT from roughly $0.0077/min, with promotional rates lower) and $200 in free credits to start, making it one of the cheapest production STT options. It's optimized for real-time, high-throughput voice applications and competes directly with AssemblyAI. Like AssemblyAI, it's infrastructure for builders, not a consumer-facing tool.
AIVA
AIVA is one of the original AI music composers, focused on editable, multi-track compositions across 250+ styles, with custom style-model training. Its standout feature is ownership: the Pro tier (EUR 49/mo, or EUR 33 billed yearly) hands you full, permanent copyright of your compositions -- something most generators don't offer. Free and Standard tiers keep copyright with AIVA and require credit, and there's no public self-serve API. Pricing is in EUR plus VAT, which makes it pricier for US buyers. It's the best pick when you need to truly own and edit what you generate.
Deepgram edges AIVA on aggregate — 86 vs 73.
Among the fastest and cheapest production speech-to-text APIs -- a developer tool, not a consumer app, and a direct AssemblyAI rival. AIVA still wins for buyers who prioritise pro tier grants full copyright ownership. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
