+ ## Model Description
16
+
17
+ The model creators note in the [associated paper](https://arxiv.org/pdf/2107.07402.pdf):
18
+
19
+ > The model is a self supervised learning based audio pre-trained model which learns cross lingual speech representations from raw audio across 23 Indic languages. It is built on top of wav2vec 2.0 which is solved by training a contrastive task over masked latent speech representations and jointly learns the quantization of latents shared across all languages.

+ # Uses
37
+
38
+
39
+ ## Direct Use
40
+ This model can be used for the task of automatic speech recognition.
41
+
42
+ ## Downstream Use [Optional]
43
+
44
+ More information needed.
45
+
46
+ ## Out-of-Scope Use
47
+
48
+ The model should not be used to intentionally create hostile or alienating environments for people.
49
+
50
+ # Bias, Risks, and Limitations
51
+
52
+
53
+ Significant research has explored bias and fairness issues with language models (see, e.g., [Sheng et al. (2021)](https://aclanthology.org/2021.acl-long.330.pdf) and [Bender et al. (2021)](https://dl.acm.org/doi/pdf/10.1145/3442188.3445922)). Predictions generated by the model may include disturbing and harmful stereotypes across protected classes; identity characteristics; and sensitive, social, and occupational groups.
54
+
55
+
56
+
57
+ ## Recommendations
58
+
59
+
60
+ Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

64
+ ## Training Data
65
+
66
+ The model creators note in the [associated paper](https://arxiv.org/pdf/2107.07402.pdf):
67
+ > All our data has been processed through the open sourced framework called Vakyansh . The basic steps of the process are -
68
+ 1.) Download and convert audio to wav format with sample rate 16000, number of channels 1 and bit rate per sample of 16.
69
+ 2.) We split an audio into voiced chunks using voice activity detection . We make sure that all the voiced chunks lie between 1 and 30 seconds.
70
+ 3.) To detect and reject noisy samples we use a signal to noise ratio (SNR) approach described by [Kim and Stern, 2008]. We consider any audio sample below a SNR value of 25 as noise and do not include them in training data.
71
+ 4.) We perform speaker and gender identification on our audio data. A high level representation of voice is learnt using a voice encoder based on [Wan et al., 2020]. For each audio sample the voice encoder creates a 256 dimensional encoding that summarizes characteristics of the spoken voice. For gender identification we train a support vector machine algorithm on the embedding with manually labelled data.
72
+
73
+ > Our goal for speaker identification was to get a sense of the number of speakers in a particular audio source. To estimate we use a hierarchical clustering approach to cluster similar embeddings in the sense of cosine similarity. The number of speakers are thus the number of clusters.
