Which architecture was used for the new Sourashtra text-to-speech models?

  1. A.VITS
  2. B.Tacotron
  3. C.WaveNet
  4. D.Transformer-XL

Correct answer

A. VITS

Explanation

The correct answer is VITS, which stands for Variational Inference with adversarial learning for end-to-end Text-to-Speech. The models built by BHASHINI and IISc Bengaluru use this architecture and generate Sourashtra speech directly from written text. They also work on character-level text, which removes the need for a separate phonemizer to convert spelling into sound units before speech is produced, and the audio they produce is at 22,050 Hz. The other three options are wrong because the release names none of them. Candidates preparing for science and technology questions should note the full expansion of VITS along with the number of models, which is four, made up of one male and one female voice, each available for the Tamil script and the Sourashtra script.

Practice Questions

Q1.Science & TechnologyEasy

BHASHINI has developed text-to-speech models for Sourashtra in collaboration with which institution?

  1. A.IIT Madras
  2. B.Indian Institute of Science, Bengaluru
  3. C.IIIT Hyderabad
  4. D.Anna University
Show answer
Correct answer: B. Indian Institute of Science, Bengaluru

The Digital India BHASHINI Division, which works under the Digital India Corporation in the Ministry of Electronics and Information Technology, built the models jointly with IISc Bengaluru, and the speech corpus used for training was developed at the institute SPIRE Lab.

Q2.Science & TechnologyMedium

Sourashtra, for which the new text-to-speech models were built, belongs to which language family and is spoken mainly in which state?

  1. A.Dravidian, Tamil Nadu
  2. B.Indo-Aryan, Tamil Nadu
  3. C.Indo-Aryan, Gujarat
  4. D.Dravidian, Karnataka
Show answer
Correct answer: B. Indo-Aryan, Tamil Nadu

The release describes Sourashtra as a minority Indo-Aryan language spoken predominantly by the Sourashtra community in Tamil Nadu, which makes it unusual: it is an Indo-Aryan tongue surviving inside a state whose major language, Tamil, is Dravidian.

Q4.Science & TechnologyMedium

Which of the following best describes how a computed tomography scanner produces its images?

  1. A.Strong magnetic fields align hydrogen nuclei in the body
  2. B.High frequency sound waves are reflected off tissue
  3. C.A rotating X-ray system with digital detectors, reconstructed by computer algorithms
  4. D.Radioactive tracers injected into the bloodstream are tracked
Show answer
Correct answer: C. A rotating X-ray system with digital detectors, reconstructed by computer algorithms

In a computed tomography machine the X-ray source turns around the patient while detectors record the radiation that passes through, and software then assembles those readings into cross-sectional pictures of the structures inside the body.

Q5.Science & TechnologyMedium

Which company has been supported for the development of an indigenous 32-slice CT scanner?

  1. A.Panacea Medical Technologies Private Limited
  2. B.Bharat Electronics Limited
  3. C.Hindustan Antibiotics Limited
  4. D.HLL Lifecare Limited
Show answer
Correct answer: A. Panacea Medical Technologies Private Limited

Building on its strength in high precision imaging, the firm has taken up the design, development and deployment of a diagnostic scanner, and the agreement with the Board will fund that effort through to commercial sale.
