By the end of this guide you will have held a conversation across two languages with live AI translation, either face to face on a phone or on an online call, and, if you use a meeting tool, you will have a transcript to look back on. A real-time translation app listens to speech, converts it into the other language as people talk, and shows the result.
If you want to translate conversations in real time with AI, the first decision is the setting: two people sharing a phone, or a video call where you need subtitles and notes. This guide walks through the steps and compares three tools from our Audio and voice and productivity categories.
Key takeaways
- For a face-to-face chat, use a phone app with a two-way conversation mode. For online meetings, use a tool that runs beside your call and shows live subtitles in your language.
- Language coverage differs by tool and even by mode within a tool, so check both languages before you rely on it.
- Free allowances are small for the meeting tools: for example, 180 free minutes a month on Speechara or 120 transcription minutes a month on Notta.
- Live translation is a convenience, not an interpreter. Confirm anything legal, medical or high-stakes with a qualified human interpreter, and tell people when you are recording.
What you need before you start
- A device. A phone for in-person talk, or a computer for online calls.
- Both languages named. The language each person speaks, since coverage varies by tool.
- A quiet place. Background noise lowers recognition quality.
- A plan that fits. Google Translate's apps and website are free to use. Speechara and Notta have free plans with monthly minute limits.
- Time. About ten minutes to set up and test, under an hour with a real practice call.
- Consent. Tell the other person if you are recording or transcribing a call, and follow local rules.
Which kind of AI tool fits this job
Pick by where the conversation happens.
A phone app for face-to-face talk. Google Translate is a free app and website for Android and iOS. Its Conversation mode lets two people speaking different languages talk through the app, and Transcribe shows translated captions of speech as it happens. You can also download languages to translate with no internet connection.
An assistant that runs beside online calls. Speechara runs beside Zoom, Google Meet, Teams, Webex or any desktop call, capturing system audio or your microphone, so no bot joins the meeting. It shows a live transcript, translates between 88 languages with subtitles, and writes a summary afterwards. It is in beta.
A transcription and notes tool for meetings. Notta records conversations, imports audio and video files and turns them into searchable text with speaker labels and AI summaries. It lists transcript translation and bilingual transcription (translation is a paid add-on on Pro and higher), and it captures Zoom, Microsoft Teams, Google Meet and Webex meetings, including bot-free recording.
Step 1: Decide the setting and the languages
You end this step knowing which kind of tool you need.
- Decide whether the conversation is in person or on a call.
- Write down the language each person speaks, including regional variants.
- Note whether you need a transcript afterwards, or only live understanding.
- Check whether anyone is uncomfortable with recording, and agree on it first.
Check it worked by writing one line, such as "in person, English to Spanish, no recording".
Step 2: Choose a tool and check language support
You end this step with an app that supports both languages in the mode you need.
- Check the language list. Google Translate says language coverage differs by mode, so text, camera and voice do not all support the same languages. Speechara lists speech recognition and translation in 88 languages.
- Check the platform. Google Translate runs on the web, Android and iOS. Speechara lists web, macOS and Windows apps, with the iPhone app in beta testing and Android in development. Notta lists web, iOS, Android and a Chrome extension.
- Check the free allowance: 180 minutes each month on Speechara, and 120 transcription minutes a month on Notta, though Notta's Free plan allows up to 3 minutes per conversation and its translation is a paid add-on on Pro and higher.
- Use the comparison table below for pricing and stated limits.
Check it worked by confirming both languages appear in the tool's list for the mode you need.
Step 3: Set up and test the audio
A short test avoids a failed conversation.
- Install the app or open it in the browser, and allow microphone access. For online calls, allow the tool to capture system audio if it asks.
- Download languages for offline use if you will travel without data. Google Translate needs a language downloaded before it works offline.
- Choose the input and output languages.
- Speak a short test sentence in each language and check the result.
Check it worked by seeing your test sentence translated correctly in both directions.
Step 4: Start the conversation
The goal is a smooth back-and-forth that both people can follow.
- For face-to-face talk, open Conversation mode in Google Translate and place the phone where both people can see it.
- For an online call, start the call as usual, then start Speechara or Notta beside it. Speechara needs no invitation and no bot.
- Speak in short sentences and pause between turns, since long run-on speech is harder to translate.
- Show the screen or read the subtitles aloud so the other person can follow.
Check it worked by the other person confirming that the translated text matches what you meant.
Step 5: Check the important points
Live translation can drift, especially with idioms and names.
- Repeat key numbers, dates, names and addresses, and have the other person repeat them back.
- Rephrase anything that came out strangely. Avoid slang and jokes.
- Clarify tone. Speechara can suggest a reply or clarify a question you were just asked, but read any suggestion before you use it.
- For legal, medical, immigration or financial matters, bring a qualified human interpreter.
Check it worked by both sides summarising the agreed points in their own words.
Step 6: Save the transcript and follow up
A record helps when memory fails or someone needs a translated version.
- Save the transcript, summary and action items. Speechara produces a summary, notes, decisions and action items, and Notta produces AI summaries.
- Edit the transcript for errors before you share it. Notta lets you edit and share transcripts, and translate them with its paid add-on.
- Delete recordings you no longer need. Speechara says it does not store audio recordings and lets you delete history at any time.
Check it worked by opening the saved transcript on another device.

Common mistakes to avoid
- Assuming every language pair works. Coverage differs by tool and by mode. Fix it by checking both languages in the exact mode you plan to use.
- Talking too fast. Long, fast sentences produce errors. Fix it by speaking in short phrases and pausing for the translation.
- Relying on it for high-stakes talk. Machine translation can miss nuance. Fix it by using a qualified interpreter for legal, medical or financial conversations.
- Recording without telling people. Consent rules vary. Fix it by saying you are recording or transcribing, and by choosing a bot-free tool only if everyone knows it is running.
- Forgetting free-plan caps. A meeting can outlast a free allowance. Fix it by checking limits such as Notta's 3 minutes per conversation before an important call.
How we put this together
This is an evidence-based guide built from each tool's listing in our directory, which is compiled from the vendor's own site and pricing page. It is not a review based on using the tools.

Frequently asked questions
Is there a free way to translate a conversation in real time?
Yes. Google Translate's apps and website cost nothing to use and include a Conversation mode. Speechara's free plan gives 180 minutes a month, and Notta's Free plan gives 120 transcription minutes a month, though Notta's translation is a paid add-on. Free allowances have limits, so check them before an important conversation.
Which app is good for real-time translation on a phone?
Google Translate runs on Android and iOS and has Conversation mode for two people speaking different languages. Notta lists iOS and Android apps for transcription. Speechara lists an iPhone app in beta testing and Android in development.
Can I translate a Zoom or Google Meet call live?
Yes, with a tool that runs beside the call. Speechara captures system audio or your microphone alongside Zoom, Google Meet, Teams and Webex, so no bot joins the meeting. Notta records those platforms too. Tell participants before you start.
Can I use live translation without internet?
Only partly. Google Translate can translate with no internet connection once a language is downloaded to the device. The listings for the other tools do not describe offline use, so check each vendor's site before you travel.
How accurate is real-time AI translation?
It is useful for everyday understanding but not guaranteed. Accuracy depends on audio quality, accents, speed and idioms. Confirm key facts, and use a qualified human interpreter for legal, medical or other high-stakes conversations.
