About
SpeechGen is a neural text-to-speech converter designed to produce high-quality, human-like audio from written text. Supporting over 140 languages and a library of more than 1,000 voices, the platform utilizes advanced AI to capture nuances in speech, including various genders, ages, and accents. It distinguishes itself by handling exceptionally long texts, allowing users to process up to two million characters in a single request, which is ideal for narrating entire books or long-form documents. The platform offers a granular suite of editing tools, including a multi-voice editor that enables complex dialogue creation within a single file. Users can fine-tune output through SSML support, adjusting parameters like speed, pitch, and pauses. For voices that support it, intonation graphs allow for visual manipulation of speech curves. A standout technical feature is the "Smart Cache" system, which stores generated sentences for seven days; if a user edits a paragraph, they are only charged for the modified sentence rather than the entire document, significantly reducing costs during the editing phase. SpeechGen is tailored for content creators on platforms like YouTube and TikTok who require professional narration without the expense of a recording studio. It is equally valuable for educators developing e-learning modules and marketers creating localized video ads. Developers can leverage the provided API to integrate voice synthesis into apps or WordPress sites. The tool also supports specialized workflows such as converting subtitle (SRT) files into timed audio and transforming PDF or DOCX documents into accessible MP3 files for on-the-go listening. Unlike many competitors that rely on monthly subscription models, SpeechGen operates on a pay-as-you-go system with one-time payments for character limits that never expire. This flexibility, combined with its ability to export high-fidelity audio in formats like MP3, WAV, and OGG, makes it a highly accessible choice for both occasional users and high-volume professional projects. The inclusion of "Pro" voices and multi-language characters—which maintain a consistent voice identity across different tongues—further solidifies its position as a versatile tool for global content creation.

FAQs
Can I use the generated audio for commercial purposes?
Yes, paid plans permit commercial use across platforms like YouTube, TikTok, Instagram, and Twitch, as well as for video ads, podcasts, and e-books.
How does the smart caching system save me money?
The system stores sentences for 7 days, so if you edit only one part of a text and regenerate, you are only charged for the new or changed sentence rather than the entire file.
Is there a limit on how much text I can convert at once?
Users with sufficient balance can convert up to 2,000,000 characters in a single query, which is approximately 300,000 words, making it ideal for books.
What is the difference between Pro and regular voices?
Pro voices utilize more advanced neural networks to provide higher naturalness, better emotional expression, and more accurate pronunciation for professional projects.
Does changing audio settings consume my character limits?
Adjusting speech speed or pitch requires full regeneration and consumes limits, but you can freely modify pauses between sentences without any limit consumption.
