TTSOpenAI

TTSOpenAI uses a credit-based pricing model with plans starting around $9/month for basic usage. OpenAI's direct API pricing is $15 per 1 million characters for TTS-1 and $30 per 1 million characters for TTS-1-HD. For context, 1 million characters equals roughly 150,000 words or about 16 hours of audio. TTSOpenAI charges a convenience premium for its web interface, which is reasonable for occasional use but becomes significant at higher volumes. If you are generating more than a few hours of audio monthly, learning to use OpenAI's API directly will save substantial costs.

TTSOpenAI uses OpenAI's TTS models, which produce clean, natural-sounding speech suitable for most professional uses including narration, presentations, and educational content. ElevenLabs generally offers more expressive voices with greater emotional range, plus features like voice cloning and speech-to-speech that TTSOpenAI lacks entirely. For basic narration and content reading, the quality difference is modest and most listeners would find both acceptable. For audiobook production, character dialogue, or use cases requiring specific voice matching and custom voice creation, ElevenLabs provides significantly more capability and flexibility, though at a higher price point and with a steeper learning curve.

TTSOpenAI provides access to OpenAI's 6 built-in voices: Alloy (neutral), Echo (warm male), Fable (storytelling), Onyx (deep male), Nova (friendly female), and Shimmer (expressive female). Each voice has distinct characteristics suited to different content types, from conversational narration to professional presentations. The platform supports over 50 languages including English, Spanish, French, German, Japanese, Chinese, Arabic, Hindi, and many others. Language is automatically detected from the input text without manual selection. All voices work across all supported languages, though voice quality and accent naturalness vary by language, with English being the most polished and natural-sounding across all six voice options.
