Yoob vs OpenAI: an OpenAI alternative

Yoob speaks the same API shape as OpenAI's audio endpoints: change the base URL and the model name, keep your code, and get emotion tags, 493 voices and transcripts that hear feeling.

What you get with Yoob

  • Emotion, sound and delivery tags written into the text: [tender], [sigh], [laughing], 17 feelings and 16 sounds.
  • 493 voices in 24 accents, 48 kHz audio, streamed over HTTP or a WebSocket that takes text as your model writes it.
  • Transcripts that carry emotion, sounds and delivery, word timings, a voice profile and a human-or-AI score.
  • OpenAI-compatible /v1/audio/speech and /v1/audio/transcriptions: switch with a base URL.
  • One key and one balance for speech, transcription, voice agents, AI-voice detection and avatars.
  • A Free plan every month: 5 minutes of speech and 10 minutes of transcription.

Where OpenAI is stronger

  • Speech and language models on one account, if you already run everything there.
  • More languages.

Switching takes two lines

from openai import OpenAI

client = OpenAI(base_url="https://tts-api.yoob.com/v1", api_key=YOOB_API_KEY)
audio = client.audio.speech.create(
    model="yoob-tts-1", voice="w1243",
    input="[excited] Okay, do not freak out. [gasp] They want me to start on Monday!")
audio.write_to_file("line.wav")
