Customer testimonials

See why creators, publishers, and teams rely on Narration Box for natural-sounding voice content.

"What I like about Narration Box is the quality of its multiple voices, which is very effective and clean. Unlike other text to speech platforms, the voices sound natural and do not have that robotic tone, especially when creating longer narrations. I also like the flexibility of choosing from a huge collection of available voices, languages, and regional accents, which made localization much easier. The editor and UI are simple to use, and the block-based workflow makes it convenient to assign different speakers, adjust pronunciations, and fine-tune pacing without redoing the entire project."

"The user-interface is great. Nice and simple without too many bells and whistles. The array of voices are also good, though some are definitely better than others. With that said, you can adjust the speaking pace for each voice, which does improve the flow, making voices seem less artificial. Also, the free plan is generous."

"The best part I like about Narration Box is that it supports multiple languages with multiple narrators. Even in my required language, that is Hindi, 7 accents are available (4 male and 3 female). I can adjust the speaking rate and style. The output created can be saved in different formats, though I need .wav mostly."

"Quality of voices and ease of use made Narration Box the perfect choice for my fiction podcast The Program. It's the only voice synthesis service that knew the difference between 'live frugally' and 'live broadcast' and that could pronounce Mar-a-Lago."
