Aivis Cloud CLI is a versatile tool designed to interact with the Aivis Cloud API, offering robust speech synthesis and audio playback capabilities. It allows users to convert text into natural-sounding speech and manage audio playback with features like synchronous and asynchronous options and queue management. A key feature is its Model Context Protocol (MCP) compatibility, enabling AI assistants like Claude to directly control audio output. The tool also supports extensive voice model management and persistent configuration for API keys and settings, making it an essential resource for developers integrating advanced voice features into their applications.
