How says Google, voice searching may be even three times faster than normal searching by typing on our phones, so it can't surprise that Google spends a lot of funds on developing this option. This time Google posted on its official blog information that voice searching will be available in 30 new languages after hours of works with native speakers to improve accuracy of searching.
All new languages are: Amharic (Ethiopia), Armenian (Armenia), Azerbaijani (Azerbaijani), Bengali (Bangladesh), English from Ghana, Kenya, Nigeria and Tanzania, Georgian (Georgia), Gujarati (India), Javanese (Indonesia), Kannada (India), Khmer (Cambodian), Lao (Laos), Latvian (Latvia), Malayalam (India), Marathi (India), Nepali (Nepal), Sinhala (Sri Lanka), Sundanese (Indonesia), Swahili (Tanzania), Tamil (India/Singapore/Sri Lanka/Malaysia), Telugu (India) and Urdu (Pakistan/India).
Whole languages are available in Cloud Speech API. In the nearest future they will appear in Google Translate and Gboard app.
