Sarvam – The blog describes Sarvam as an open‑source voice AI stack that delivers multilingual text‑to‑speech synthesis, built on community contributions and designed for Indian language coverage, allowing developers to tailor voice output without licensing fees.

AI4Bharat – According to the article, AI4Bharat provides an open‑source speech‑recognition engine that supports dozens of regional dialects, offering a DIY alternative to commercial APIs and emphasizing low‑cost deployment for local applications.

Bhasini – The post notes Bhasini focuses on low‑resource language models, delivering voice synthesis where data is scarce, and highlights its community‑driven training pipeline that can be adapted quickly for new Indian languages.

IndicTTS – The analysis compares IndicTTS’s open dataset and toolkit with commercial offerings, concluding that DIY stacks excel in customization and cost savings but may lack the robustness and large‑scale support that paid services provide.
