What is Bland Speech v3?

Bland Speech v3 represents a cutting-edge text-to-speech technology designed to produce voice audio that mimics human speech closely, especially useful in scenarios like phone conversations where overly polished tones might feel disingenuous. This advanced model incorporates vital human characteristics such as breathing patterns, stutters, pauses, laughter, and throat-clearing by employing performance tags that are performed rather than merely recited. Users have the flexibility to either input their own scripts or make use of the Director feature to outline a dialogue, enabling Bland to meticulously shape the conversation's timing, structure, and delivery before the speech is generated. In addition to these features, the model provides voice cloning capabilities: a quick clone can be created from around 10 seconds of audio, while more professional-grade cloning necessitates at least 30 minutes of confirmed audio, during which users must verify ownership of the voice. Furthermore, Bland Speech is accessible through a web-based studio and a single API endpoint /v1/speak, which requires bearer-key authentication to ensure secure access. The audio is delivered using HTTP chunked transfer or WebSocket protocols, resulting in PCM16 WAV files at a 44.1 kHz sample rate, which guarantees excellent quality for various applications. This multifaceted functionality positions Bland Speech as a crucial resource for developers aiming to elevate their audio production capabilities, making it an indispensable solution in the realm of text-to-speech technologies.
