Production Economics

Voice AI that moves you from demo‑ware to production realities.

Voice systems behave very differently at scale. Once latency budgets tighten, usage spikes, and compliance kicks in, architectural decisions start to dominate outcomes. MARS8 is built for these real‑world constraints, not for API convenience.

BENCHMARK RESULTS

Redefining the new baseline in TTS

Run the benchmarks yourself →
CER ↓

Percentage of characters that are incorrect in the generated output, as measured by Whisper ASR.

WavLM SV cosine similarity↑

Speaker similarity metric measured as the mean cosine similarity between generated audio and reference audio, using the wavlm-base-sv embedding model.

CAM++ cosine similarity ↑

Speaker similarity metric measured as the mean cosine similarity between generated audio and reference audio, using the CAM++ embedding model.

CE ↑

Approximate mean opinion score on a 1–10 scale, predicted by Meta’s Audiobox‑Aesthetics model; higher CE reflects greater content enjoyment.

PQ ↑

Approximate mean opinion score on a 1–10 scale, predicted by Meta’s Audiobox‑Aesthetics model; higher PQ indicates better production quality.
