Trying to train telugu audio dataset from scratch on vits

[naveed81]

My dataset is a multi speaker one. Below is my training script:
import os

from trainer import Trainer, TrainerArgs

from TTS.tts.configs.shared_configs import BaseDatasetConfig
from TTS.tts.configs.vits_config import VitsConfig
from TTS.tts.datasets import load_tts_samples
from TTS.tts.models.vits import Vits, VitsArgs, VitsAudioConfig

from TTS.bin.compute_embeddings import compute_embeddings
from TTS.tts.utils.data import get_length_balancer_weights
from TTS.tts.utils.languages import LanguageManager, get_language_balancer_weights
from TTS.tts.utils.speakers import SpeakerManager, get_speaker_balancer_weights, get_speaker_manager

output_path = os.path.dirname(os.path.abspath(file))
dataset_config = BaseDatasetConfig(
formatter="vctk", meta_file_train="", phonemizer="espeak", language="te", path=os.path.join(output_path, "te_male")
)

audio_config = VitsAudioConfig(
sample_rate=22050, win_length=1024, hop_length=256, num_mels=80, mel_fmin=0, mel_fmax=None
)

vitsArgs = VitsArgs(
use_speaker_embedding=True,
)

INITIALIZE THE AUDIO PROCESSOR

Audio processor is used for feature extraction and audio I/O.

It mainly serves to the dataloader and the training loggers.

ap = AudioProcessor.init_from_config(config)

INITIALIZE THE TOKENIZER

Tokenizer is used to convert text to sequences of token IDs.

config is updated with the default characters if not defined in the config.

tokenizer, config = TTSTokenizer.init_from_config(config)

LOAD DATA SAMPLES

Each sample is a list of [text, audio_file_path, speaker_name]

You can define your custom sample loader returning the list of samples.

Or define your custom formatter and pass it to the load_tts_samples.

Check TTS.tts.datasets.load_tts_samples for more details.

train_samples, eval_samples = load_tts_samples(
dataset_config,
eval_split=True,
eval_split_max_size=config.eval_split_max_size,
eval_split_size=config.eval_split_size,
)

init speaker manager for multi-speaker training

it maps speaker-id to speaker-name in the model and data-loader

speaker_manager = SpeakerManager()
speaker_manager.set_ids_from_data(train_samples + eval_samples, parse_key="speaker_name")
config.model_args.num_speakers = speaker_manager.num_speakers

init model

model = Vits(config, ap, tokenizer, speaker_manager)

init the trainer and 🚀

trainer = Trainer(
TrainerArgs(),
config,
output_path,
model=model,
train_samples=train_samples,
eval_samples=eval_samples,
)
trainer.fit()

So far I have completed 7000 steps and audio I am getting in tensorboard is gibberish (doesnt sound like telugu). Attached samples. What am I doing wrong? Please correct me.

Below are the audio samples after 7000 steps of training. It doesnt sound like Telugu at all, its all gibberish.

[naveed81]

I fixed it by not using phonemes. If anyone wants a detailed explanation, drop a msg.

[Rakshitha-Ummadisetti]

Can you please provide detailed explanation!
Thanks in advance
