Google Cloud Text-to-Speech vs TTSReader

Google Cloud Text-to-Speech is an API that converts text or SSML into audio data for applications. It offers more than 380 voices across more than 75 languages and variants, with REST or gRPC integration and output formats including MP3, LINEAR16, OGG_OPUS, MULAW, and ALAW. Gemini-TTS supports single- or multispeaker speech guided by natural-language prompts for style, accent, pace, tone, and emotional expression. Chirp 3 instant custom voice can create a personalized voice model from as little as 10 seconds of audio and is available in more than 30 locales. Streaming synthesis supports real-time conversations, while long-audio synthesis accepts up to 1 million bytes of input. Speech controls include pitch, speaking rate, and volume gain. Billing counts input characters, including spaces, newlines, and SSML tags except the mark tag, and billing must be enabled. Standard and WaveNet voices cost US$4 per 1 million characters, with 0 to 4 million characters free. Other voice models have different rates and free-use limits. New customers can receive $300 in Google Cloud credits.

TTSReader converts text and documents into speech, reads webpages aloud, and can create downloadable audio. It supports PDF, DOCX, TXT, CSV, and EPUB files, with MP3 and WAV listed as export formats and a maximum input of 200000. Voices come from Google, OpenAI, xAI, Microsoft, and proprietary AI providers. During playback, the reader highlights the current text and remembers the article and position so listening can resume later. Users can edit text while it plays and combine voices, languages, and speeds in one file. The service identifies proofreading, education, accessibility, language learning, audiobook creation, and voice-over production as uses. Its website plugin is free and includes playback controls, voice and speed selection, automatic scrolling, and saved preferences; the maker says it does not track users, use cookies, or show ads. API access is available, though the synchronous API recommends only a few thousand characters, calls 5k safe, and notes requests can time out after five minutes. The Free plan costs nothing and is for personal use only, with 5k premium-voice characters. Premium is $10.99 a month for one user and 1,000,000 premium characters per month. Pay-as-you-go plans cost $10 a month for 200,000 characters, $32 a month for 1,000,000, or $300 a month for 10,000,000; credits expire after one year, extended by each new purchase.
