What is a Voice Changer?
Voice Changer, a new model from Cartesia, can convert the speech of any audio clip into other timbres while preserving the emotion and expression of the original audio. Users can choose from a variety of high-quality voice libraries provided by Cartesia, or clone their own voices, and have complete control over the details of the speech, such as articulation, emotion, and rhythm. Voice Changer is suitable for creators to produce unique content, voice acting for characters in games and entertainment, converting audiobooks and podcasts for listeners, and creating branded audio for businesses. Voice Changer is based on a state-space model architecture, providing high-quality audio generation and processing capabilities.

The technical principle of Voice Changer
Voice Changer is based on Cartesia's pioneering work on the State Space Models (SSM) architecture. SSM is an advanced method for processing and generating high-resolution data (such as audio), characterized by the following features:
- Data representationSSM represents data as a sequence of states that change over time, which can more effectively capture and simulate the dynamic characteristics of audio signals.
- Sequence processingSSM can process long sequences of data, which is crucial for generating coherent and natural speech.
- Cost-effectivenessThe SSM architecture offers near-linear scaling costs, and the cost increase is manageable when processing longer sequences.
- High-quality generationSSM can generate high-quality audio thanks to the precise simulation and control of audio signals.
- Flexibility and controlSSM provides fine-grained control over the audio generation process, enabling Voice Changer to achieve precise voice transformation and emotional preservation.
