Swarodaya, Swar Vigyan or Swara Shastra is method of prediction based on Swara (roughly translated to vowels). This astrology doesn't require birth details for predictions and hence useful for the people who do not know their date, time or place of birth. Swarodaya primarily uses name of a living or non-living things for predictions and hence as far as application is concerned Swarodaya is quite similar to Numerology. Swarodaya is used more often for mundane predictions and the predictions related to winning and losing, commodity and share market predictions etc. Swarodaya is also very useful for muhurat (auspicious time) finding. Swarodaya originated primarily from Tantra and we can clearly see tantra influence on it. Yamal Tantra texts have covered Swarodaya extensively. Narapatijayacharya is a comprehensive compilation of scattered Swarodaya texts.
