Text-to-Speech
Text-to-speech (TTS) is the technology that converts written text into synthesized spoken audio, enabling computers and AI systems to communicate verbally through natural-sounding voices.
理解する Text-to-Speech
Early TTS systems produced robotic, clearly artificial speech that limited their usefulness. Modern neural TTS systems generate speech that is nearly indistinguishable from human voices, with natural prosody, appropriate emphasis, and convincing emotional variation. This quality improvement has made TTS viable for professional AI assistants, voice interfaces, and accessibility applications. Key TTS providers include ElevenLabs, OpenAI TTS, Microsoft Azure Speech, and Google Cloud TTS. Neural TTS models are trained on hours of voice recordings to capture natural speech patterns.
GAIAの活用方法 Text-to-Speech
GAIA's voice agent uses text-to-speech to provide spoken responses, enabling a fully voice-based interface. When you interact with GAIA verbally, it processes your speech, generates a response, and delivers it as natural-sounding audio. This creates a hands-free experience suitable for driving, cooking, or any situation where reading a screen is inconvenient.

AIアシスタント
AIアシスタントとは、普段の言葉で伝えた依頼を理解し、実際に行動するソフトウェアです。質問に答えるだけでなく、メールの下書きと送信、会議の設定、タスクの管理、複数ステップのワークフローの実行まで、すでに使っているアプリの中で行います。Siri、Alexa、Googleアシスタント、ChatGPT、GAIAはいずれもAIアシスタントですが、違いはそれぞれがどれだけ実際の作業を代わりにこなせるかにあります。
