About Sonantic

Sonantic is an AI voice company positioned at the intersection of entertainment and synthetic speech. Founded to serve story-driven industries, it built its reputation by producing highly expressive voices that aim to mimic actor performances, including granular control over emotion, breath, and pauses. Sonantic attracted attention for licensed character voices and cinematic deliverables and was acquired into a larger audio technology ecosystem (announced in 2022). Its core value proposition is making voice synthesis that sounds like directed performances rather than generic TTS, enabling creators to iterate dialogue and direction without re-recording actors for every take.

The product offers several specific capabilities. Sonantic Studio (web) provides line-by-line controls where users can adjust pitch, emphasis, timing, and emotional intensity; it exports WAVs for DAWs and supports batch rendering of dialogue lines. The API exposes programmatic generation for dynamic, runtime speech in games and interactive experiences and provides SDKs for Unity and Unreal Engine to stream or pre-render audio assets. Sonantic also offers custom voice creation (voice cloning) from recorded source material — the company states usable results from a small set of clean samples (sample-length guidance is provided during onboarding). Additional features include phoneme-level editing, SSML-like markup for direction, and secure asset management for enterprise projects.

Sonantic does not list a single flat-rate consumer price on its site; instead it offers a free demo experience on the web and negotiates production and enterprise plans directly with buyers. For evaluation you can use the in-browser demo and request access to Studio; paid plans are typically volume- and license-based with per-minute, per-seat, or project pricing depending on use case (contact sales for exact quotes). Enterprise customers get SLA, support, commercial voice licenses, and custom voice builds. Because pricing is tailored, teams should expect to discuss intended delivery formats, projected hours of generated audio, and distribution scope during procurement.

Users include game audio directors who use Sonantic to produce hundreds of NPC lines with consistent character performance, and film post-production supervisors who create alternate dialogue tracks or provisional ADR. Other real-world workflows include narrative designers dynamically generating branching dialogue in Unity and VO teams preparing audition-style synthetic reads for director review. For teams comparing options, Sonantic leans toward cinematic realism and integration with game engines, whereas competitors like Replica Studios may emphasize simpler self-serve interfaces and transparent per-minute pricing.

What makes Sonantic different

Three capabilities that set Sonantic apart from its nearest competitors.

  • Cinematic emphasis: Sonantic focuses on actor-style emotional performances at phoneme level for narrative projects.
  • Game-engine SDKs: Official Unity and Unreal integrations allow runtime streaming or pre-rendered dialogue pipelines.
  • Enterprise licensing: Sonantic offers bespoke voice creation and commercial license terms negotiated per-project.
