Everything you need to know about our GPT-4o mini TTS service.
GPT-4o mini TTS is OpenAI's most advanced Text to Speech model, capable of converting written text into remarkably natural-sounding speech. It's built on neural network architecture that understands context, emotion, and linguistic nuances to deliver human-like voice output.
HiTTS.cc leverages the cutting-edge GPT-4o mini TTS model to provide superior voice quality, more natural-sounding speech, emotional expressiveness, and contextual understanding that other services can't match. Our user-friendly interface, comprehensive API, and flexible pricing also set us apart from competitors.
GPT-4o mini TTS supports over 40 languages, including English, Spanish, French, German, Japanese, Mandarin, Hindi, Arabic, Portuguese, and many more. All supported languages benefit from the same high-quality, natural-sounding speech synthesis.
HiTTS.cc supports multiple audio formats including MP3, WAV, OGG, and FLAC. You can choose the format that best suits your needs, whether you're prioritizing audio quality or file size optimization.
Yes! Depending on your plan, you can access various voice options and customize parameters such as speech rate, pitch, and emphasis.
Absolutely. We prioritize data security and privacy. Your content is encrypted during transmission and processing. We don't store your text or generated audio beyond the processing period.
Speech Instructions are optional directives you can provide to customize how the AI voice delivers your text. You can specify tone (cheerful, serious), style (like a news broadcaster, movie trailer), pace (slow, energetic), and emotional qualities. The GPT-4o mini TTS model interprets these instructions and adjusts the speech generation accordingly, creating more nuanced and contextually appropriate audio output.
Yes! You can combine multiple instructions to create highly customized voice outputs. For example, you might request "Speak slowly and clearly with a cheerful tone, gradually becoming more excited toward the end." The AI will attempt to incorporate all aspects of your instructions. We recommend experimenting with different combinations to find the perfect voice style for your content.
The most effective instructions are clear, specific, and contextually appropriate for your content. Instructions about emotional tone (cheerful, serious, excited), speaking style (professional, conversational), pace (slow, fast), and voice quality (soft, authoritative) typically work well. You can also reference familiar speaking styles like "narrate like a documentary" or "speak like a teacher explaining a concept." The AI performs best with natural language instructions that describe how a human would deliver the speech.
HiTTS.cc supports all audio formats offered by OpenAI's TTS API:
Choose MP3 for general use, Opus for streaming, AAC for mobile compatibility, FLAC for highest quality, WAV for professional editing, and PCM only if you need raw audio data.
