Translation Process

Translation requires many hands.

Accuracy and accessibility begin with the translation process.

It doesn’t matter if we’re translating one verse or one hundred, there are many, many steps that must happen in the translation process. Far more than in text-to-text translation.

For each translation, our team follows an 14-step plan that involves several video iterations, many comprehension assessments, and post-production polishing.

Step 1

Exegetical research
Our exegetical team researches ideas, themes, and relevant background information which is important to the translation.

This critical step allows the translator to accurately portray the Biblical text in context so viewers can fully grasp and understand its meaning.

Step 2

Initial draft
After the translator discusses the passage with the exegetical team, the first draft of the translation is recorded. This is the moment that text first becomes sign!

This is usually not done in a single shot. The clips are then edited together to create an initial draft. This critical step gives the translator a clear mental image of the content so they can sign it clearly.

Step 3

Revisions and re-recording
This happens several times throughout the translation process and is usually the step that takes the most time and effort. Revisions are made to:
  • Fix errors in meaning
  • Tweak signed names or terms
  • Clarify or prevent misinterpretation
  • Correct inconsistencies
  • Rearrange to better fit JSL linguistics

Step 4

Comprehension check
This check is included early in the process when working with new translators. We invite members of the Deaf community, both those who are not Christian and those who are, to view the drafts and tell us what they understand the draft to mean. This valuable feedback helps ensure that the translation can be accessible to anyone regardless of familiarity with Christianity or scripture.

Step 5

Revisions and re-recording
These revisions are based on what we learned from the community comprehension check. We revise and re-record to:
  • Fix errors in meaning
  • Tweak signed names or terms
  • Clarify or prevent misinterpretation
  • Correct inconsistencies
  • Rearrange to better fit JSL linguistics

Step 6

Consultant check
Trained translation consultants check the drafts at various points in the translation process and works closely with the team to address any potential problems that arise. It's important for our team to receive third-party feedback from someone trained in exegesis, linguistics, and sociocultural aspects that may impact the translation.

Step 7

Revisions and re-recording
This happens several times throughout the translation process and is usually the step that takes the most time and effort. Revisions are made to:
  • Fix errors in meaning
  • Tweak signed names or terms
  • Clarify or prevent misinterpretation
  • Correct inconsistencies
  • Rearrange to better fit JSL linguistics

These revisions based on feedback from the translation consultant are usually via SLTT, a video annotation web app. In addition, online or in person discussions also take place.

Step 8

Comprehension check
By this point the draft should look fairly seamless. At this community check we focus on ensuring the translation doesn’t appear stilted but flows naturally allowing viewers to understand the content accurately.

Again, we invite both Christian and non-Christian individuals from the Deaf community to come back to view our updated drafts and give us feedback.

Step 9

Revisions and re-recording
This step is crucial for the translation to be accurately understood. Strained and unnatural language patterns cause confusion and can lead to errors in interpreting what the scripture says.

Based on the feedback we receive in the previous step, we revise and re-record to:
  • Fix errors in meaning
  • Tweak signed names or terms
  • Clarify or prevent misinterpretation
  • Correct inconsistencies
  • Rearrange to better fit JSL linguistics

With this revision, the feedback is usually given through annotation web app called SLTT online. Of course, if the time difference works out, they also meet online or in person to further discuss some of the points.

Step 10

Final consultant check
After reviewing the new draft, translation consultants offer suggestions for any necessary additional edits.
1

Step 11

Revisions and re-recording
After revisions are made based on the final consultant check, the signers practice shadowing the entire draft in preparation for the final recording.

We sometimes re-record the entire chapters so that the signers can shadow them smoothly. When we do, we will run it by the consultant again.

Step 12

Final recording
Once the drafts are finalized, we’re ready for the last recording. When we’re drafting, we insert revised snippets into the draft video. Not this time. For this final recording sometimes one take will be an entire chapter or sizable section of scripture. This is fundamental in producing a high-quality translation that is consistent from one passage to the next.

Besides recording, this step involves additional preparation; lighting and technical set up, as well as caring for make-up, hair and wardrobe for the signer.

Step 13

Post-production
Our team imports the final video clips to the computer for final editing. Sometimes images and captions are added to help with meaning and context. Scripture references are added in the corner.

Step 14

Publishing
Finally, the scripture is ready to be published and viewed. Our team publishes the final videos on YouTube and through our free app available for your mobile device.

This process can take months, even years, to complete – especially without the funding and support needed.

The team met in person from October 5–8 and completed the first round of drafting for chapters 11 and 12, as well as part of chapter 13. Since we have a new on-screen signer for chapters 11–16, we began by helping them become more familiar with the content of chapters 1–10. We also revisited some Bible-specific concepts, such as what “gifts” and “speaking in tongues” mean, what it means for each person to be part of the body of Christ, and what the Lord’s Supper is. As we worked through these concepts, we carefully considered how best to express them in Japanese Sign Language. The team consists of an on-screen signer, two sign language checkers, an exegetical researcher, and an exegesis support member. We are grateful that everyone was able to contribute their individual strengths, work well together as a team, and enjoy the translation process. Our next in-person translation sessions are scheduled for October 26–30.

We are currently working on the first draft of Revelation 6–11. During our in-person translation sessions in September, we were able to work through Revelation 6:1–7:14 in this first draft. In sign languages, it is important to clearly understand where people and objects are located and to use the space in front of the signer to represent those relationships. Where something comes from, where it moves, and how it moves can all be important to the meaning. In Revelation, this means carefully considering the relationships between the Lamb, the horses and their riders, the four living creatures, the souls of the people, and many other elements—where they are, how they relate to one another, and where each event is taking place. As we translate, we are carefully following the flow of the text and working through these details in context. Taking the time to work through all of this carefully requires a great deal of patience, focus, and stamina. Please pray for our translation team as they continue this challenging work.

The process of getting scripture off the page, into sign, onto video, and into the hands of the community is intensive. Not only does it require special knowledge and skill, it also requires expensive equipment and extensive time from our team members.

Our team is aiming to have the entire New Testament completely translated and published by 2032. As of August 2026, we’re 89.14% there.

Overall, our team is 39.57% done with the entire Bible.
