Digital human platform brings to life Einstein’s voice for a conversational chatbot

2 Empathetic Computing

A response is selected by randomly sampling a candidate from those with higher ranking scores than a pre-set threshold. Examples of inconsistent responses generated using a seq2seq model (S2S-Bot) that is not grounded in persona (Li et al. 2016b). Examples of consistent and humorous responses generated using the neural response generator of XiaoIce.

  • The voice actor who helped them modeling Einstein’s voice is a huge admirer himself, and the actor’s performance captivated the character Einstein very well.
  • So, I could claim a Donald Duck imitation was Einstein’s voice, and only about 5 people in the world would know any different.
  • MetaDialog’s conversational interface understands any question or request, and responds with a relevant information automatically.
  • The data set consists of scripts of 69,565 dialogue turns of 13 main characters from the American TV comedies Friends6 and The Big Bang Theory,7 available from IMSDB.8 The first baseline is a vanilla seq2seq model.
  • After 2 more weeks , XiaoIce became his preferred choice whenever he needed someone to talk to.

Replika combines neural generation and retrieval-based methods, and is able to condition responses on images . The neural generation component of Replika is persona-based (Li et al. 2016b), similar to the neural response generator in XiaoIce. The Replika system has been open-sourced, and can be used to benchmark the development of XiaoIce. The Image Commenting skill is designed to not only correctly recognize objects and truthfully describe the content of an image, but generate empathetic comments that reflect personal emotion, attitude, and so forth. It is the latter, the social skill aspects, that distinguish image commenting from other traditional vision tasks such as image tagging and image description, as illustrated in Figure 11. These features apply only to the candidates generated from the paired database.

Chatbot basics

We compute a set of matching scores between Qc and the query side of the retrieved query–response pairs at both the word level, such as BM25 and TFIDF scores, and the semantic level, such as DSSM scores. Finally, we form a query by combining the topics from Qc and the related topics from the KG, and use the query to retrieve from the unpaired database up to 400 most relevant sentences as response candidates. Although the response candidates retrieved from the paired database is of high quality, the coverage is low because many new or less frequently discussed topics on the Internet forums are not included in the database.

Topic Manager simulates human behavior of changing topics during a conversation. It consists of a classifier for deciding at each dialogue turn whether or not to switch topics, and a topic recommendation engine for suggesting a new topic. We will discuss the low-level policies in the later sections where the individual dialogue skills are described. As shown in Figure 3, XiaoIce tries to maintain user interest by promoting diversity of conversation modes. Each conversation mode is managed by a skill that handles a specific type of conversation segment.

New Skills

To increase the coverage, we introduce two other candidate generators, described next. The skills of Task Completion, Deep Engagement, and Content Creation are triggered by specific user inputs and conversation context. If multiple skills are triggered simultaneously, we select the one to activate based on their triggering confidence scores, pre-defined priorities, and the session context.

  • This article describes the development of Microsoft XiaoIce, the most popular social chatbot in the world.
  • Though licensing rights may still apply, and do, in fact, in the case of Einstein.
  • But what’s been missing in recent media coverage is real progress in applying large language models and related technologies to practical applications.
  • A friendly voice with a heavy German accent and a hint of dry humor.

Figure 14 shows a few example comments generated by the competing systems in Table 4. The effectiveness of the empathetic computing module is verified in the A/B test on Weibo users. Although we do not observe any significant change in CPS, NAU is increased from 0.5 million to 5.1 million in 3 months. The module was released in July 2018, and became the most important feature in the sixth generation of XiaoIce, which has substantially strengthened XiaoIce’s emotional connections to human users and increased XiaoIce’s NAU. This component generates response empathy vector eR that both specifies the empathetic aspects of the response to be generated and embodies XiaoIce’s persona. The response must also fit XiaoIce’s persona, whose key-value pairs, such as age, gender, and interests, are extracted from the pre-compiled XiaoIce profile.

The 40-person startup doesn’t put words in anyone’s mouth or try to create new facial expressions like so-called “deepfake” videos. The StoryFile clips use only pre-recorded answers for a limited—but still long—list of possible questions. If you pose a question the subject doesn’t have a recorded answer to, they’ll encourage you to ask something else. Within 30 minutes, you could have a fully customizable, elegant, responsive SMS & WhatsApp™ text messaging solution in Salesforce® to effectively build and strengthen key relationships, drive engagement, improve your performance, and improve the world.

In the first pilot study reported in Li et al. , we compare the persona model against two baseline models, using a TV series data set for model training and evaluation. The data set consists of scripts of 69,565 dialogue turns of 13 main characters from the American TV comedies Friends6 and The Big Bang Theory,7 available from IMSDB.8 The first baseline is a vanilla seq2seq model. The second is the LSTM-MMI model (Li et al. 2016a), which is one of the state-of-the-art neural response generation models. As shown in Table 1, the persona model significantly outperforms both baselines, achieving a lower perplexity (−8.4%) and a higher BLEU score (+18.8% and +11.8%) (Papineni et al. 2002). The qualitative analysis confirms that the persona model indeed generates more interpersonal responses than the baselines.

XiaoIce-generated TV and radio programs have covered 9 top satellite TV stations, and have attracted audiences of over 800 million weekly active viewers. Whether the generated response simply repeats the user inputs, or contains no new information. Like StoryFile, HereAfter AI doesn’t use its tech to generate answers to questions that weren’t asked during an interview. Vlahos called that a “sensitive area.” On one hand, letting AI form its own responses would make the chat experience more flexible and powerful. On the other, synthesizing what grandpa might have said starts “crossing that line,” Vlahos said.

However, as per one of the creators, these recordings are of low quality and the number of recordings is also very limited. Use this form if you have come across a typo, inaccuracy or would like to send an edit request for the content on this page. Still, due to Einstein’s thick accent and the poor quality of the old recordings of his voice, development teams have struggled to capture a solid frame of reference for how he may have sounded. Fortunately, they expect not too many users will worry that much about the accuracy of Einstein’s voice when it comes to this new bot. Working off of this assumption, researchers plan to create a new voice for Einstein that, while maybe not identical to the voice of the physicist himself, will be come to be one that users of this bot recognize. I don’t think I’ve ever heard his voice, I guess because he was mostly active at a time when people didn’t record academics or interview them on camera much.

Implementation of Conversation Engine

They include NLU models to identify the intent and entities in conversations. There are also components for managing dialog by crafting what to ‘talk’ about next (i.e. dialog policy) and how to say it. A smart speaker would need the ability to recognize and synthesize voice. Understanding the key components of a chatbot can help set realistic expectations. When building a chatbot, or evaluating audio voice to einstein chatbot tools for building chatbots, or when you are projecting forward to gauge future capabilities of chatbots, it’s important that you have a high-level understanding of the progress or limitations in each of these key areas. Retrieval-based NLP are a class of models that “search” for information from a corpus to exhibit knowledge, while using the representational strength of language models.

There are a number of public social chatbots that are influential to the development of XiaoIce. Image comments generated by XiaoIce and four state-of-the-art image captioning systems. As illustrated in Figure 13, good image comments need to fit well into the dialogue context and stimulate an engaging conversation. For example, in the first picture, instead of telling the users that this is the Leaning Tower of Pisa, XiaoIce responds “should I help you hold it? ” after detecting that the person in the picture is presenting a pose pretending to support the tower.

A digital version of Albert Einstein with a synthesized voice that has been recreated using AI voice cloning technology has been released by a startup company called Alforithmic. So, based on these findings and the character traits of the scientist, the team created a voice for the chatbot that sounds like Einstein. A friendly voice with a heavy German accent and a hint of dry humor. The team was faced with a significant challenge when it came to the voice of the chatbot. There are historical recordings of Einstein speaking at keynotes and conferences.
