## Dataset Description
|
| 22 |
+
|
| 23 |
+
This dataset contains transcribed high-quality audio of Tamil sentences recorded
|
| 24 |
+
by volunteers. It is part of the [OpenSLR](https://www.openslr.org) collection of
|
| 25 |
+
free speech resources for low-resource languages.
|
| 26 |
+
|
| 27 |
+
The data was collected via the
|
| 28 |
+
[Appen](https://appen.com) (formerly Figure Eight / CrowdFlower) crowdsourcing
|
| 29 |
+
platform and is intended for use in training automatic speech recognition (ASR)
|
| 30 |
+
and text-to-speech (TTS) systems.
|
| 31 |
+
|
| 32 |
+
### Data Collection
|
| 33 |
+
|
| 34 |
+
Volunteers were asked to read Tamil sentences displayed on their screen and
|
| 35 |
+
record themselves. Quality control was performed to ensure accurate transcriptions
|
| 36 |
+
and clean audio.
