For more synthesized audios, please refer to [PaddleSpeech Text-To-Speech samples](https://paddlespeech.readthedocs.io/en/latest/tts/demo.html). Via the easy-to-use, efficient, flexible and scalable implementation, our vision is to empower both industrial application and academic research, including training, inference & testing modules, and deployment process. To be more specific, this toolkit features at: - **Fast and Light-weight**: we provide high-speed and ultra-lightweight models that are convenient for industrial deployment. - **Rule-based Chinese frontend**: our frontend contains Text Normalization and Grapheme-to-Phoneme (G2P, including Polyphone and Tone Sandhi). Moreover, we use self-defined linguistic rules to adapt Chinese context. - **Varieties of Functions that Vitalize both Industrial and Academia**: - *Implementation of critical audio tasks*: this toolkit contains audio functions like Speech Translation, Automatic Speech Recognition, Text-To-Speech Synthesis, Voice Cloning, etc. - *Integration of mainstream models and datasets*: the toolkit implements modules that participate in the whole pipeline of the speech tasks, and uses mainstream datasets like LibriSpeech, LJSpeech, AIShell, CSMSC, etc. See also [model lists](#models-list) for more details. - *Cascaded models application*: as an extension of the application of traditional audio tasks, we combine the workflows of aforementioned tasks with other fields like Natural language processing (NLP), like Punctuation Restoration. # Community You are warmly welcome to submit questions in [discussions](https://github.com/PaddlePaddle/DeepSpeech/discussions) and bug reports in [issues](https://github.com/PaddlePaddle/DeepSpeech/issues)!

# Alternative Installation The base environment in this page is - Ubuntu 16.04 - python>=3.7 - paddlepaddle>=2.2.0-rc If you want to set up PaddleSpeech in other environment, please see the [installation](./docs/source/install.md) documents for all the alternatives. # Quick Start Developers can have a try of our model with only a few lines of code. A tiny DeepSpeech2 **Speech-To-Text** model training on toy set of LibriSpeech: ```shell cd examples/tiny/s0/ # source the environment source path.sh source ../../../utils/parse_options.sh # prepare data bash ./local/data.sh # train model, all `ckpt` under `exp` dir, if you use paddlepaddle-gpu, you can set CUDA_VISIBLE_DEVICES before the train script ./local/train.sh conf/deepspeech2.yaml deepspeech2 offline # avg n best model to get the test model, in this case, n = 1 avg.sh best exp/deepspeech2/checkpoints 1 # evaluate the test model ./local/test.sh conf/deepspeech2.yaml exp/deepspeech2/checkpoints/avg_1 offline ``` For **Text-To-Speech**, try pretrained FastSpeech2 + Parallel WaveGAN on CSMSC: ```shell cd examples/csmsc/tts3 # download the pretrained models and unaip them wget https://paddlespeech.bj.bcebos.com/Parakeet/pwg_baker_ckpt_0.4.zip unzip pwg_baker_ckpt_0.4.zip wget https://paddlespeech.bj.bcebos.com/Parakeet/fastspeech2_nosil_baker_ckpt_0.4.zip unzip fastspeech2_nosil_baker_ckpt_0.4.zip # source the environment source path.sh # run end-to-end synthesize FLAGS_allocator_strategy=naive_best_fit \ FLAGS_fraction_of_gpu_memory_to_use=0.01 \ python3 ${BIN_DIR}/synthesize_e2e.py \ --fastspeech2-config=fastspeech2_nosil_baker_ckpt_0.4/default.yaml \ --fastspeech2-checkpoint=fastspeech2_nosil_baker_ckpt_0.4/snapshot_iter_76000.pdz \ --fastspeech2-stat=fastspeech2_nosil_baker_ckpt_0.4/speech_stats.npy \ --pwg-config=pwg_baker_ckpt_0.4/pwg_default.yaml \ --pwg-checkpoint=pwg_baker_ckpt_0.4/pwg_snapshot_iter_400000.pdz \ --pwg-stat=pwg_baker_ckpt_0.4/pwg_stats.npy \ --text=${BIN_DIR}/../sentences.txt \ --output-dir=exp/default/test_e2e \ --inference-dir=exp/default/inference \ --phones-dict=fastspeech2_nosil_baker_ckpt_0.4/phone_id_map.txt ``` If you want to try more functions like training and tuning, please see [Speech-To-Text Quick Start](./docs/source/asr/quick_start.md) and [Text-To-Speech Quick Start](./docs/source/tts/quick_start.md). # Models List PaddleSpeech supports a series of most popular models, summarized in [released models](./docs/source/released_models.md) with available pretrained models.
