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

Inworld AI's Realtime TTS-2 represents a cutting-edge voice model designed for instantaneous dialogue, aiming to create a conversational experience that is as human-like as it sounds. This innovative system captures the entirety of an interaction, analyzing the user’s tone, rhythm, and emotional nuances, while also allowing developers to provide voice direction using simple English commands, similar to prompting an AI model. Unlike traditional speech generation that operates in isolation, this model incorporates the context of previous exchanges, ensuring that tone and pacing evolve throughout the conversation, meaning a response can have a completely different impact depending on the preceding context, such as humor or sadness. Furthermore, the Voice Direction feature empowers developers to guide the delivery of speech as a director would with an actor, using intuitive natural language rather than rigid emotion controls or sliders. Additionally, developers can integrate inline nonverbal cues like [sigh], [breathe], and [laugh] directly into the text, which the model seamlessly transforms into corresponding audio events. Notably, Realtime TTS-2 maintains a consistent voice identity across over 100 languages, allowing for smooth language transitions within a single interaction, enhancing its applicability in diverse multilingual settings. This capability ensures that conversations remain fluid and authentic, further bridging the gap between human and machine communication.
