Thanks for making the time. I want to start with framing — what was the original hypothesis behind the project?

S2

Honestly, maybe forty percent. The shape held — the mechanics underneath had to be rebuilt almost entirely.

95%+ on clear English. It holds up on real-world recordings too.

Modern transcription reaches 95%+ word accuracy on clear English at 128 kbps and above, comparable to a human transcriber on the same recording. The audio coming in sets the ceiling — cleaner source, cleaner transcript. The breakdown below covers the recordings we actually see in production.

Common questions

6 things people ask about this.

01Que bitrates MP3 están soportados?+
Todos os bitrates MP3 estándar de 32 kbps a 320 kbps, tanto de bitrate constante (CBR) como variable (VBR). A precisión é mellor a 128 kbps e por riba. Por debaixo de 64 kbps, a compresión perceptiva comeza a afectar a precisión das palabras — planifica unha revisión manual para gravacións con esa calidade.
02Converter o meu MP3 a WAV primeiro mellora a precisión?+
Non. Converter un MP3 a WAV non recupera a información de audio perdida durante a codificación MP3. Se tes a gravación orixinal en WAV ou un formato sen perdas, úsaa directamente para obter resultados lixeiramente mellores. Pero un MP3 estándar a 128 kbps+ é un material fonte excelente por si mesmo.
03Cal é o tamaño máximo de ficheiro MP3?+
Free: 100 MB e ata 30 minutos por ficheiro (o que chegue primeiro). Pro: 2 GB e ata 10 horas por ficheiro (aproximadamente 8–9 horas a 128 kbps). Business: 5 GB e ata 10 horas por ficheiro. Para arquivos de varios ficheiros, envía cada ficheiro como un traballo API separado — Pro executa ata 20 traballos simultáneos, Business ata 50.
04Podo obter un ficheiro SRT desde un MP3?+
Si. Exporta SRT ou VTT directamente desde a páxina de transcrición — útil para volver cargar subtítulos en YouTube, incrustar subtítulos nunha edición de vídeo ou arquivar transcricións con marcas de tempo. As marcas de tempo aliñan con posicións no MP3 orixinal.
05Canto tempo leva transcribir un MP3?+
Un MP3 de 60 minutos normalmente complétase en 60–120 segundos. Os ficheiros longos divídense en fragmentos e procésanse en paralelo — un ficheiro de 4 horas non leva 4× máis. Os ficheiros do plan Business reciben procesamento prioritario.
06Funciona para MP3s que non están en inglés?+
Si — 100+ idiomas, detectados automaticamente nos primeiros 30 segundos de audio. Os idiomas de nivel 1 (inglés, castelán, alemán, francés, portugués, italiano, neerlandés, polaco) ofrecen 95%+ de precisión en calquera MP3 de bitrate estándar. Os de nivel 2 (ruso, xaponés, mandarín, coreano e outros 13) ofrecen precisión de calidade de produción.
