Whisper es un modelo de vanguardia para el reconocimiento automático de voz (ASR) y la traducción de voz, propuesto en el artículo «Reconocimiento de voz robusto mediante supervisión débil a gran escala» de Alec Radford et al. de OpenAI. Entrenado con más de 5 millones de horas de datos etiquetados, Whisper muestra una fuerte capacidad de generalización a diversos conjuntos de datos y dominios en un contexto de cero disparos. Whisper large-v3-turbo es una versión ajustada de un Whisper large-v3 simplificado. En otras palabras, es el mismo modelo exacto, excepto que el número de capas de decodificación se ha reducido de 32 a 4. Como resultado, el modelo es mucho más rápido, a expensas de una ligera reducción de la calidad.
The OpenAI-compatible Audio transcription API endpoint allows you to recognize and transcribe audio, especially human speech, into text.
Audio transcription is a technology that converts spoken language into written text. It is a complex process that involves several stages, including speech signal preprocessing, feature extraction, acoustic modeling, language modeling, and speech recognition engine.
AI Endpoints makes it easy, with ready-to-use inference APIs. Discover how to use them:
The API accepts multiple audio formats, including:
Make sure your file is in one of these formats before sending it for transcription.
The Audio transcription endpoint offers you a wide range of transcription options for audios. Learn how to use them with the following examples:
First, export your access token to the OVH_AI_ENDPOINTS_ACCESS_TOKEN environment variable:
export OVH_AI_ENDPOINTS_ACCESS_TOKEN=<your-access-token>If you do not have an access token key yet, follow the instructions in the AI Endpoints – Getting Started.
The whisper-large-v3-turbo API is compatible with the OpenAI specification.
First install the openai library:
pip install openaiNext, export your access token to the OVH_AI_ENDPOINTS_ACCESS_TOKEN environment variable:
export OVH_AI_ENDPOINTS_ACCESS_TOKEN=<your-access-token>Finally, run the following Python code:
import os
from openai import OpenAI
url = "https://oai.endpoints.kepler.ai.cloud.ovh.net/v1/"
audio_file_path = "my_audio.mp3"
client = OpenAI(
base_url=url,
api_key=os.getenv('OVH_AI_ENDPOINTS_ACCESS_TOKEN')
)
audio_file = open(audio_file_path, "rb")
transcript_answer = client.audio.transcriptions.create(
model="whisper-large-v3-turbo",
file=audio_file,
temperature=0.0
)
print(transcript_answer)Which returns the following:

}When using AI Endpoints, the following rate limits apply:
On top of the request rate limitations, AI Endpoints also applies the following limitations to the audio data:
If you exceed these limits, different HTTP error codes will be returned depending on the type of limitation exceeded:
Note that exceeding either the rate limit or audio size/duration limits will result in an appropriate error response to help you understand and address the issue.
If you require higher usage, please get in touch with us to discuss increasing your rate limits.
