Description

Bland Speech v3 is an innovative text-to-speech model that aims to generate voice audio that closely resembles that of a human, particularly in contexts like phone calls where overly polished speech may come off as inauthentic. This model captures essential human elements such as breathing, stutters, pauses, laughter, and throat-clearing by utilizing performance tags that are acted out rather than simply read. Users have the option to input their own scripts or utilize the Director feature to outline a conversation, allowing Bland to craft the dialogue, timing, and delivery prior to speech generation. Additionally, it offers voice cloning capabilities: a quick clone can be made from approximately 10 seconds of audio, whereas professional-grade cloning requires 30 minutes or more of verified audio, with users affirming that each voice belongs to them. Bland Speech can be accessed via a web studio and a single /v1/speak API endpoint, which employs bearer-key authentication for security. Audio is streamed through HTTP chunked transfer or WebSocket, returning PCM16 WAV files at a sample rate of 44.1 kHz, ensuring high-quality output for diverse applications. This versatility makes Bland Speech an essential tool for developers looking to enhance their audio experiences.

Description

The gpt-4o-mini-realtime-preview model is a streamlined and economical variant of GPT-4o, specifically crafted for real-time interaction in both speech and text formats with minimal delay. It is capable of processing both audio and text inputs and outputs, facilitating “speech in, speech out” dialogue experiences through a consistent WebSocket or WebRTC connection. In contrast to its larger counterparts in the GPT-4o family, this model currently lacks support for image and structured output formats, concentrating solely on immediate voice and text applications. Developers have the ability to initiate a real-time session through the /realtime/sessions endpoint to acquire a temporary key, allowing them to stream user audio or text and receive immediate responses via the same connection. This model belongs to the early preview family (version 2024-12-17) and is primarily designed for testing purposes and gathering feedback, rather than handling extensive production workloads. The usage comes with certain rate limitations and may undergo changes during the preview phase. Its focus on audio and text modalities opens up possibilities for applications like conversational voice assistants, enhancing user interaction in a variety of settings. As technology evolves, further enhancements and features may be introduced to enrich user experiences.
