Murf AI

Speech Arena Elo (text-to-speech), Falcon 2: 1157 Elo (95% interval -12/12), rank 27 of 98

Same blind-vote arena as above. Murf Speech Gen 2 scores 986 (rank 82).

Source: Artificial Analysis API. tag:src:Independent. Published 2026-10-27; read 2026-10-27.

Quote: “API fields: name "Falcon 2", elo 1157, rank 27, ci95 "-12/12".”

Limit: Listener votes, not a controlled test; the arena rates one model's voices, not Murf's editing studio or workflow.

Pronunciation accuracy, Speech Gen 2: 99.37%

Murf's Gen 2 API page. An independent blind test across five languages, 300,000 news sentences. Two native speakers scored each word. The separate benchmark page's heading says 99.38% and does not name Falcon or Gen 2 in that line.

Source: Gen 2 model page (Murf API docs). tag:ven:Vendor-reported. Published ; read 2026-10-28.

Quote: “achieving 99.37% pronunciation accuracy”

Limit: Vendor-reported. The listeners had no stated tie to Murf on this page, but Murf designed the test and published the number. It is not the Falcon 2 Speech Arena Elo.

Naturalness win rate against five other TTS vendors: wins 8 of 10 language comparisons; 60% vs ElevenLabs in English

Murf's own benchmark page. Blind pairs, native listeners hired through a third party, more than 11,000 pairs. Ties excluded. English (US, UK, AU, IN) win rates: AWS 68%, ElevenLabs 60%, Google 78%, Azure 71%, OpenAI 50%. German vs ElevenLabs 66%. French vs ElevenLabs 80%.

Source: TTS model benchmarking (Murf). tag:ven:Vendor-reported. Published ; read 2026-10-28.

Quote: “8 out of 10 times Murf voices win on naturalness vs. competition”

Limit: Vendor-reported. Murf chose the voices, scripts and competitors. German vs AWS is 14% on the same table, so the headline is not a win in every language.

No. Every figure was run by someone else and recorded as printed on the source page. BestSuperintelligent has not reproduced any of them, so a different version or sample can give a different number.

Why do some products have no result?

We found no independent test we could read and cite for them as of 27 October 2026. That is not evidence that a product performs well or badly, only that no usable test was found.

How is this different from the benchmark records?

Benchmark records are numbers vendors publish about their own models. These are tests run by outside parties such as academics, independent labs and journalists, so we keep the two lists apart.
