Frequently Asked Questions

We currently support 9+ languages, including: Simplified Chinese, English, Spanish, French, German, Italian, Japanese, Korean, Portuguese. We are continuously expanding language support and will add more languages in the future. All supported languages can be used as source or target languages.

Yes, this is our core feature. Through advanced AI speech synthesis technology, we can analyze and preserve the timbre, tone, speed, and emotional characteristics of the original speech. Translated speech sounds like the original speaker speaking in the target language, rather than standard machine-synthesized voice. This is VoiceOver Speech's biggest advantage over other translation services.

We support multiple common audio formats, including MP3, WAV, M4A, OGG. Maximum file size is 50MB per file. We recommend using MP3 or WAV format, as these formats have the best compatibility and fastest processing speed.

Yes, we support two methods: 1) Upload existing audio files; 2) Use real-time recording function. In the console, click the "New Task" button, select "Record" mode, then click the microphone button to start recording. After recording is complete, you can directly upload it for translation, which is very convenient.

Yes, our service can handle audio with multiple speakers. However, for best results, we recommend: 1) Clear audio with minimal background noise; 2) Speakers identify themselves before speaking; 3) Use separate microphones if possible. The system will preserve each speaker's voice characteristics in the translation.

Yes, our AI system is trained on diverse datasets including various accents and dialects. While standard accents work best, we can handle many regional variations. If you encounter issues with specific accents, please contact support and we can work on improving recognition for your use case.

It's very simple: 1) Log in with Google or Microsoft account; 2) Upload audio file or use real-time recording; 3) Select target language; 4) Click "Start Translation"; 5) After processing is complete, view, play, or download results in the translation history. The entire process usually takes only a few minutes.

Translation time depends on audio length. Usually 1 minute of audio requires 1-2 minutes of processing time. Shorter audio (within 30 seconds) is usually completed within 30 seconds. Longer audio (over 5 minutes) may take 5-10 minutes. You can check task status in the console's translation history, and you will receive a notification when complete.

After translation is complete, you can view all tasks in the "Translation History" in the console. Each task will display: original audio, translated audio, original text transcription, translated text transcription. You can click the play button to preview audio, or click the download button to save the translated audio file. You can also expand to view detailed subtitle content.

Yes. You can upload multiple audio files one by one, and the system will process them in order. All tasks will be saved in the translation history for unified management. You can also select multiple tasks for batch download or delete operations.

Our translation accuracy can reach over 95% in standard environments. Accuracy is affected by various factors: audio quality, speech clarity, background noise, accent, etc. We recommend using clear recordings, avoiding background noise, and maintaining natural speaking speed for the best translation results.

There is no strict maximum length limit, but we recommend keeping audio files under 30 minutes for optimal processing speed and quality. Very long files (over 1 hour) may take longer to process. You can split long audio into segments if needed.

Currently, you can view the translated text transcription in the translation history, but direct editing is not available in the interface. However, you can download the translated audio and use external tools to edit if needed. We are working on adding text editing features in future updates.

Credit consumption = audio duration (seconds). For example, 30 seconds of audio will consume 30 credits, and 1 minute of audio will consume 60 credits. New users receive 500 free credits upon registration, which can translate about 8 minutes of audio. If credits are insufficient, you can recharge through the credit purchase page.

You can obtain credits through the following methods: 1) New users receive 500 free credits upon registration; 2) Recharge through the credit purchase page; 3) Participate in our referral program (if enabled). Credit purchases support multiple packages with reasonable prices, and credits are credited immediately after purchase.

Currently, credits do not expire and you can use them at any time. However, we recommend planning credit usage reasonably and prioritizing translating important audio. If your account is inactive for a long time, we may contact you to confirm account status.

We use the latest speech recognition and speech synthesis technology from Microsoft Azure AI Speech Services. These technologies are based on deep learning and neural networks, which can accurately recognize speech content and generate natural and fluent translated speech. We also use advanced personal voice preservation technology to ensure translated speech maintains original voice characteristics.

We take user data security very seriously. All audio files are stored in encrypted Azure Blob Storage, and databases use encrypted storage and access control. We strictly comply with data protection regulations, and user audio files are automatically deleted 30 days after translation. We will not use your audio for any purpose other than providing services.

If translation fails, please check the following: 1) Is the audio file corrupted? 2) Is the audio format supported? 3) Is the file size over 50MB? 4) Does the account have sufficient credits? If the problem persists, please check the error message or contact our technical support team. We will reply to your question within 24-48 hours.

For typical audio files (under 10MB), a standard broadband connection (5 Mbps or higher) is sufficient. Larger files may require faster connections. The upload time depends on file size and your internet speed. We recommend using a stable connection for best results.

Our voice preservation technology can maintain 90-95% of original voice characteristics including timbre, tone, and speaking style. The accuracy depends on audio quality, speaker clarity, and language pair. High-quality recordings with clear speech produce the best voice preservation results.

We provide free credits for new users to experience. New users receive 500 free credits upon registration, which can translate about 8 minutes of audio. If you need more credits, you can recharge through the credit purchase page. Our pricing is very reasonable, 1 credit = 1 second of translation duration.

Yes, we offer multiple credit packages with volume discounts. For specific prices and discount information, please visit the credit purchase page. We also periodically launch limited-time promotional activities. Follow our website or email notifications to get the latest discount information.

Translation history will be saved in your account until you actively delete it. Audio files will be automatically deleted 30 days after translation is complete, but translation records (including file names, languages, status, etc.) will be retained. We recommend regularly cleaning up unnecessary history records to save storage space.
