Sv2tts online program

By Dan Avery For Dailymail. Easily available software can imitate a person's voice with such accuracy that it can fool both humans and smart devices, according to a new report. One of the programs, known as SV2TTS, only needs five seconds' worth to make a passable imitation, according to its developers. Described as a 'real-time voice cloning toolbox,' SV2TTS was able to trick Microsoft Azure about 30 percent of the time but got the best of both WeChat and Amazon Alexa almost two-thirds, or 63 percent, of the time. It was also able to fool human ears: volunteers asked to identify the real voices from the deepfakes were tricked about half the time. The deepfake audio was more successful at faking women's voices and those of non-native English speakers, though, 'why that happened, we need to investigate further,' SAND Lab researcher Emily Wenger told New Scientist.

How to Create a Voice Clone with the Real-Time-Voice-Cloning Toolbox on Windows


Voice Cloning. From a recording of someone talking, the software is able to then replicate his or her. Deepfake voice cloning technology takes a snippet of your voice and uses it to say certain words, even though you didn't actually say these words.

Neural Voice Cloning with a Few Samples. Clone your voice for free. Advances in deep learning have introduced a new wave of voice synthesis tools, capable of producing audio that sounds as if spoken by a target speaker.

If successful, such tools in the wrong hands will enable a range of powerful attacks against both humans and software systems aka machines. This paper documents efforts and findings from a comprehensive experimental study on the impact of deep-learning based speech synthesis attacks on both human listeners and machines such as speaker recognition and voice-signin systems. We find that both humans and machines can be reliably fooled by synthetic speech, and that existing defenses against synthesized speech fall short.

These findings highlight the need to raise awareness and develop new protections against synthetic speech for both humans and machines. Our voice conveys so much more than the words we speak. Hearing our voice is often enough for a listener to make inferences about us, such as gender appearance Pernet and Belin, , size or strength Sell et al.

But perhaps the human voice is no longer as unique as we would like to believe. Recent advances in deep learning have led to a wide range of tools that produce synthetic speech spoken in a voice of a target speaker, either as text-to-speech TTS tools that transform arbitrary text into spoken words Wang et al.

In addition to proprietary systems like Google Duplex, many others are available as open source software or commercial web services 46 ; Given the strong ties between our voices and our identities, a tool that successfully spoofs or mimics our voices can do severe damage in a variety of settings.

First, it could bypass voice-based authentication systems also called automatic speaker verification systems already deployed in automated customer service phonelines for banks and credit card companies e. It would also defeat user-based access controls in IoT devices such as digital home assistants e. Finally, such tools could directly attack end users, by augmenting traditional phishing scams with a familiar human voice. This apparently was the case in a recent scam, where attackers used the mimicked voice of a corporate CEO to order a subordinate to issue an illegitimate money transfer Stupp, These speech synthesis attacks, particularly those enabled by advances in deep learning, pose a serious threat to both computer systems and human beings.

Yet, there has been — until now — no definitive effort to measure the severity of this threat in the context of deep learning systems. Prior work has established the viability of speech synthesis attacks against prior generations of synthesis tools and speaker recognition systems Masuko et al.

Similarly, prior work assessing human vulnerability to speech synthesis attacks evaluates now-outdated systems in limited settings Mukhopadhyay et al. We believe there is an urgent need to measure and understand how deep-learning based speech synthesis attacks impact two distinct entities: machines e.

Can such attacks overcome currently deployed speaker recognition systems in security-critical settings? Or can they compromise mobile systems such as voice-signin on mobile apps?

Against human targets, can synthesized speech samples mimicking a particular human voice successfully convince us of their authenticity? In this paper, we describe results of an in-depth analysis of the threat posed to both machines and humans by deep-learning speech synthesis attacks. We begin by assessing the susceptibility of modern speaker verification systems including commercial systems Microsoft Azure, WeChat, and Alexa and evaluate a variety of factors affecting attack success.

To assess human vulnerability to synthetic speech, we perform multiple user studies in both a survey setting and a trusted context. Finally, we assess the viability of existing defenses in defending against speech synthesis attacks. All of our experiments use publicly available deep-learning speech synthesis systems, and our results highlight the need for new defenses against deep learning-based speech synthesis attacks, for both humans and machines.

Key Findings. Our study produces several key findings:. An interview-based deception study of 14 participants shows that, in a more trusted setting, inserted synthetic speech successfully deceives the large majority of participants. Detailed evaluation of 2 state-of-the-art defenses shows that they fall short in their goals of either preventing speech synthesis or reliably detecting it, highlighting the need for new defenses.

It is important to note that speech synthesis is intrinsically about producing audible speech that sounds like the target speaker to humans and machines alike. This is fundamentally different from adversarial attacks that perturb speech to cause misclassification in speaker recognition systems Chen et al. Such attacks do not affect human listeners, and could be addressed by developing new defenses against adversarial examples. In this section, we first describe current trends in speaker recognition technology and voice synthesis systems, followed by voice-based spoof attacks.

Finally, we briefly summarize defenses proposed to combat synthetic speech. How Humans Identify Speakers via Voice. Though human speaker identification is imperfect, it is highly accurate and has inspired the construction of speaker recognition systems for security purposes Sharma et al. Automated User Verification by Machines. Recently, speaker recognition has become a popular alternative to other biometric authentication methods Rosenberg, If there is a match, the recognition system grants the speaker access.

Early speaker recognition systems ss used parametric methods like Gaussian Mixture Models, while more recent systems onward use deep learning models, which reduce overhead and improve accuracy Furui, ; Reynolds et al.

Speaker recognition is used in numerous settings, from bank customer identification to mobile app login and beyond 12 ; 24 ; 4. Recently, virtual assistants like Alexa and Google Assistant have begun to use speaker recognition to customize system behavior 94 ; Speaker recognition systems are either text-dependent or text-independent Bimbot et al.

Text-dependent systems use the same, speaker-specific authentication phrase for both enrollment and login. Text-independent systems are content-agnostic. Synthetic speech is produced by a non-human source i. Efforts to produce electronic synthetic speech go back to s, where Homer Dudley developed the first vocoder Mullennix and Stern, Since then, systems like Festvox Anumanchipalli et al.

The recent deep learning revolution has catalyzed growth in this field. Numerous deep neural network DNN based speech synthesis systems have been proposed Wang et al.

TTS systems transform arbitrary text into words spoken in the voice of a target speaker Wang et al. In contrast, VC systems take two voice samples — an attacker and target — and output a speech sample in which content from the attacker is spoken in the voice of the target Rebryk and Beliaev, ; Wu et al. Efficacy and Availability. Supporting evidence of DNN synthesis performance comes from real-world anecdotes. DNN-based synthetic speech has been successfully used at least one in highly profitable attack Stupp, Some DNN synthesis systems and their training datasets remain internal to companies, but many systems are available on Github C.

Jemine ; K. Qian ; 49 ; For the less tech-savvy, online services will perform voice cloning for a fee 46 ; This combination of speech synthesis efficacy and availability is both exciting and worrisome. Misuse of Speech Synthesis. There are many positive uses for speech synthesis technology, such as giving voices to the mute, aiding spoken language translation, and increasing human trust of helper robots Anumanchipalli et al.

A parallel line of work explores adversarial attacks , in which an adversary adds inaudible perturbations to speech to fool speaker recognition systems Chen et al. While powerful, adversarial attacks differ from spoofing attacks because they do not mimic the target and so pose no threat to humans.

Figure 1 gives a high-level overview of spoofing attacks. There are several techniques the adversary could use, and these are taxonomized in Table 1. Prior work has found that all spoofing techniques — replay, impersonation, and synthesis — can reliably fool machine-based voice recognition systems, but only a few works have investigated the threat posed to humans.

Here, we summarize prior work that studied these spoofing attacks. Spoofing Attacks Against Machines. Replay attacks have high overhead since the attacker must obtain specific recordings of the victim. While effective, these attacks have high overhead and limited versatility due to their dependence on human talent.

However, the efficacy of classical synthesis attacks against modern speaker recognition systems remains unclear. It performed preliminary tests by running 10 synthesized samples for 6 speakers generated by Jia et al. It produced vague conclusions: these speaker recognition prototypes produce more errors when running on synthesized speech compared to clean non-synthesized speech. Spoofing Attacks Against Humans. Existing work assessing human susceptibility to spoofing only evaluates impersonation and classical synthesis attacks.

The first classical synthesis attack measurement paper Mukhopadhyay et al. A follow-up study to this Neupane et al. They find no statistically significant differences in neural activity when real or synthetic speakers are played.

Numerous defenses have been proposed to defend speech recognition systems against synthetic speech attacks. While most have focused on detecting synthetic speech or speakers Zhang et al. No comprehensive study exists today that studies the threat posed by DNN-based speech synthesis to software-based speaker recognition systems and human users.

Our work addresses this critical need, and outlines future work needed to mitigate the resulting threat. Here, we describe the threat model, and the methodology, tools and datasets used by our analysis. When A knows T personally, these speech clips could also be obtained from private media. Next, A inputs S T to a speech synthesis system, which produces synthesized or fake voice samples S A.

In this case, S A should sound like T but contain arbitrary speech content chosen by A. We make the following assumptions about the adversary A :. A only needs a small volume of speech samples from T , i. A directly uses a publicly available, DNN-based voice synthesis system to generate synthetic speech S A ;. A seeks to generate fake voice samples S A that make either humans or machines believe that they are interacting with T. These include:. In the following, we describe the DNN synthesis and SR systems as well as speaker datasets used by our experiments.

Generalization is critical to low-resource attackers like the ones defined by our threat model, as it allows flexibility in target choice. This is a zero-shot, text-independent voice conversion system requiring only five seconds of target speech Jia et al. To generate new voices and speech patterns, Google would need to train the system again. The Figure depicts the model, which includes an encoder, an attention-based decoder, and a post-processing net. Tacotron 2. To build librosa from source, say python setup.
