            We explore self-supervised pre-training with unlabeled speech data and data augmentation to improve direct
            speech-to-speech model training. We take advantage of a recently proposed speech-to-unit translation (S2UT)
            framework that encodes
            target
            speech into discrete representations, and study both speech encoder and discrete unit decoder pre-training
            as well as
            efficient partial finetuning methods. We conduct experiments under various data setups and show that
            self-supervised
            pre-training consistently improves model performance compared with multitask learning and is complementary
            to data
            augmentation techniques that apply ASR and MT models to create weakly supervised training data.

        <p> We provide ground truth source and target audios with the corresponding reference text,
            as well as audio samples from three systems: <br>
            (1) <strong>S2UT+LNA-D</strong>: the proposed direct speeech-to-unit translation
            system initialized with wav2vec 2.0 encoder, unit mBART decoder and finetuned using LNA-D strategy<br>
            (2) <strong>Supervised S2UT</strong>: a baseline direct speech-to-unit translation system trained with
            source and target text as auxiliary task targets.
            <br>
            (3) <strong>S2T+TTS:</strong> a baseline cascaded system with a speech-to-text translation model initialized
            with wav2vec 2.0 encoder and a randomly initialized decoder, followed by a text-to-speech synthesis model. <br>
            Both (1) and (2) use an open sourced HiFi-GAN vocoder to convert units to waveforms.

        <p> We provide ground truth source and target audios with the corresponding reference text,
            as well as audio samples from three systems. All the three models are initialized with wav2vec 2.0 encoder,
            unit
            mBART decoder and finetuned using LNA-D strategy but use different datasets for finetuning: <br>
            (1) <strong>S2UT_Base</strong>: finetuned on the combination of CoVoST2, Europarl-ST, mTEDx datasets.
            <br>
            (2) <strong>S2UT_LR</strong>: finetuned on low resource setup with 50hr of data sampled from the the
            combination of CoVoST2, Europarl-ST, mTEDx datasets
            <br>
            (3) <strong>S2UT_Aug:</strong> finetuned on the the combination of CoVoST2, Europarl-ST, mTEDx datasets
            datasets plus the ASR data. <br>
            All models use an open sourced HiFi-GAN vocoder to convert units to waveforms.

        <p> We provide ground truth source and target audios with the corresponding reference text,

            (1) <strong>S2UT+LNA-D</strong>: the proposed direct speeech-to-unit translation
            system initialized with wav2vec 2.0 encoder, unit mBART decoder and finetuned using LNA-D strategy<br>
            (2) <strong>Supervised S2UT</strong>: a baseline direct speech-to-unit translation system trained with
            source and target text as auxiliary task targets.
            <br>
            (3) <strong>S2T+TTS:</strong> a baseline cascaded system with a speech-to-text translation model initialized
            with wav2vec 2.0 encoder and a randomly initialized decoder, followed by a text-to-speech synthesis model. <br>
            Both (1) and (2) use an open sourced HiFi-GAN vocoder to convert units to waveforms.

        <p> We provide ground truth source and target audios with the corresponding reference text,
            as well as audio samples from three systems. All the three models are initialized with wav2vec 2.0 encoder,
            unit
            mBART decoder and finetuned using LNA-D strategy but use different datasets for finetuning: <br>
            (1) <strong>S2UT_Base</strong>: finetuned on the combination of Europarl-ST, MuST-C datasets.
            <br>
            (2) <strong>S2UT_LR</strong>: finetuned on low resource setup with 50hr of data sampled from the combination
            of Europarl-ST, MuST-C datasets
            <br>
            (3) <strong>S2UT_Aug:</strong> finetuned on the combination of Europarl-ST, MuST-C datasets plus the ASR
            data. <br>
            All models use an open sourced HiFi-GAN vocoder to convert units to waveforms.
