在使用Amazon Connect VoiceID时，可以使用ListSpeakerEnrollmentJobs API获取说话者列表，该API返回speakerId与电话号码的映射。以下是一个示例：

import boto3

client = boto3.client('voiceid')

# Set up the request parameters
params = {
    'MaxResults': 10,
    'JobStatus': 'COMPLETED'
}

# Get the list of speaker enrollment jobs
response = client.list_speaker_enrollment_jobs(**params)

speaker_ids = {}

# Extract the speaker IDs and phone numbers from the response
if 'SpeakerEnrollmentJobs' in response:
    for job in response['SpeakerEnrollmentJobs']:
        speaker_id = job['SpeakerId']
        phone_number = job['DataAccessRoleArn'].split(':')[-1]
        speaker_ids[phone_number] = speaker_id

# Use the phone number to get the corresponding speaker ID
phone_number = '+1234567890'
speaker_id = speaker_ids.get(phone_number)

if speaker_id is None:
    print(f'No speaker ID found for phone number {phone_number}')
else:
    print(f'Speaker ID for phone number {phone_number} is {speaker_id}')

在此示例中，我们首先使用ListSpeakerEnrollmentJobs API获取说话者列表，然后将speakerId与电话号码的映射提取到一个字典中。然后，我们可以使用电话号码从字典中获取相应的speakerId。如果找不到speakerId，则输出一条消息表示找不到。
