oss-codes/voice-cost

voice-cost is the source code for a website called voice.oss.codes, which helps people figure out how much it costs to build products that use voice AI. It is built with Astro, a tool for making fast static websites, and generates 52 separate pages. Those pages include calculators for pricing out realtime speech-to-speech AI and traditional speech pipelines that combine separate speech-to-text, language model, and text-to-speech steps. There are also pages comparing pricing across different AI providers side by side, a long written guide about voice AI costs in general, profiles of nine open source voice frameworks, and profiles of twelve alternative commercial platforms. On top of that, there are regional pages covering pricing in India, the United States, and Europe, a page explaining the site's methodology, and a page about the creator and the project itself. The site also publishes a file at /llms.txt, which is a plain text index meant to be read by AI language models rather than humans. Every price listed on the site links back to its original source, such as an official provider page, and the site shows the date that price was last checked. When the underlying data changes, both the pricing information and the verification details describing when it was checked are meant to be updated together, based on rechecking the official sources. The project can be run locally using the Bun JavaScript runtime, with commands to install dependencies, run a development server, run tests including end to end tests, run a type and lint check, build the site, and preview the built output. Pricing numbers live in one data file and information about frameworks and alternative platforms lives in another. The README is fairly short and does not mention a license.
