OpenAI has launched new tools and models to facilitate the creation of voice agents, moving beyond text-based interactions. The release includes three new models: two state-of-the-art speech-to-text models, GPT-40 Transcribe and GPT-4 Mini Transcribe, which outperform previous models like Whisper in accuracy across multiple languages. These models are priced competitively at 6 cents and 3 cents per minute, respectively. Additionally, a new text-to-speech model, GPT-40 Mini TTS, allows developers to control not only what is said but also how it is said, offering customizable voice outputs. This model is available for 1 cent per minute. OpenAI also updated its Agents SDK to simplify converting text agents into voice agents, requiring minimal code changes. These advancements aim to enhance the development of reliable, flexible, and human-like voice experiences, with practical applications in customer support, language learning, and more.
