Whisper to zaawansowany model rozpoznawania mowy (ASR) i tłumaczenia mowy. Powstał na podstawie pracy "Robust Speech Recognition via Large-Scale Weak Supervision" autorstwa Aleca Radforda i zespołu OpenAI. Został wytrenowany na podstawie ponad 5 milionów godzin nagrań opatrzonych etykietami, co pozwala mu skutecznie rozpoznawać mowę w różnych zestawach danych w trybie zero-shot.
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 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 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
# You can use the model dedicated URL
url = "https://whisper-large-v3.endpoints.kepler.ai.cloud.ovh.net/api/openai_compat/v1"
# Or our unified endpoint for easy model switching with optimal OpenAI compatibility
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 = client.audio.transcriptions.create(
model="whisper-large-v3",
file=audio_file
)
print(transcript)Which returns the following:
