Particle is a news app that aggregates information from thousands of sources and distills headlines into concise, customizable summaries so busy readers can understand more, faster. Particle uses AI throughout the app to produce accurate bullet-point digests, power interactive Q&A, and identify bias and political leanings. Users can also listen to their Particle newsfeeds with the "Listen to the News" feature, powered by Inworld TTS.

The problem
Making premium voice selection economically viable
Particle knew they wanted a selection of voices for 'Listen to the News,' both for personal preferences and to appeal to their international audience. However, existing TTS solutions were prohibitively expensive, and offering multiple premium voices at scale required finding a provider that could deliver quality without breaking the economics of a subscription feature.
The team evaluated their options and found that most providers would make the breadth of voice selection they envisioned financially impractical. A dealbreaker for a feature designed to delight paying subscribers.
The solution
Expanding voice options with Inworld TTS
Particle chose Inworld TTS to power its premium voices given the combination of high quality, high speed, and competitive pricing. The integration process took only a couple of days end-to-end, immediately working smoothly and efficiently for users.
With Inworld, Particle could offer a variety of voices across different accents, genders, and languages, while cutting costs by over 80% compared to other providers.
“Through our partnership with Inworld, we have realized savings in excess of 80%, compared to other providers' costs, while maintaining exceptionally high quality.”
