In their own words
CereProc
CereProc provides text-to-speech technology for personal use, business applications, and assistive devices. Its voice library includes multilingual and accented voices with emotional synthesis. CereWave AI uses deep neural networks to generate speech and offers controls for language, gender, accent, and age. CereVoice Cloud converts text through a web interface or API using purchased credits; users can play, save, and download audio. The maker lists customer service, education, content creation, and assistive technology as Cloud applications. SDKs support Windows, macOS, Linux, Android, and iOS, with online and offline operation. The cServer supports MRCP v1/v2, Microsoft SAPI 5, and C, C++, and Python clients, and is listed for Windows and RPM-based Linux distributions. CerePlay is available for Android, iOS, iPadOS, and Apple M-series Macs. CereVoice Cloud's listed plan costs £12.99 a month for 1,000,000 characters. There is no free plan. Commercial SDK users are directed to sales, and Windows SAPI5 and macOS voices are being deprecated.
Fish Audio
Fish Audio provides text-to-speech, voice cloning, speech-to-text, voice agents, and other audio tools. Its text-to-speech controls cover emotion and expression, real-time generation, multilingual output, speed, volume, and model parameters. Fish Audio says TTS supports eight languages with native accents and its platform hosts more than 2,000,000 voices. Developers can use the API for speech generation, voice cloning, and transcription through REST, WebSocket streaming, and official Python and TypeScript SDKs.

Use cases named by the company include video voiceovers, audiobook narration, character voices, and conversational chatbots. The Free Tier costs nothing and allows 8,000 monthly credits, up to 7 minutes of generation, and personal, non-commercial use. Plus costs $11 a month, billed $132 billed annually; paid plans are listed from $15/mo. Commercial use is listed as available.
