About Speech to Text
Last updated: May 2026
OptiPix Speech to Text convierte palabras habladas en texto escrito en tiempo real utilizando la API Web Speech Recognition. Haz clic en 'Empezar a escuchar' para iniciar la transcripción en vivo desde tu micrófono. Soporta más de 50 idiomas. El modo continuo sigue escuchando hasta que lo detengas. Los resultados provisionales se muestran en gris mientras que los resultados finales aparecen en negro. Edita la transcripción, copia al portapapeles o descarga como archivo .txt. Chrome envía el audio a Google para su procesamiento; Safari procesa en el dispositivo para máxima privacidad.
How It Works
La herramienta utiliza la API Web Speech Recognition (SpeechRecognition/webkitSpeechRecognition). Captura audio de tu micrófono, lo envía al motor de reconocimiento de voz del navegador y devuelve el texto transcrito con resultados provisionales y finales.
